LM324N

AD8604DRUZ is an Analog Devices DigiTrim rail-to-rail quad operational amplifier — for precision single-supply signal conditioning: rail-to-rail input and output, very low offset voltage, single-supply operation, low input bias current, 14-lead TSSOP package. The rail-to-rail input and output maximize dynamic range on low single supplies, so sensor interfaces use the full ADC span without a negative rail; very low offset voltage keeps DC accuracy without trimming. Business impact: quad precision op amps are the workhorse of industrial and medical analog front ends — a PRODUCTION-status part with family-wide pin compatibility de-risks long-lifecycle designs. Selection advice: the DRUZ code is the 14-lead TSSOP — the AD8601, AD8602 and AD8604 are the single, dual and quad members of the family; for lower supply current consider the AD8605 family.

LM324DT is an STMicroelectronics quad low-power operational amplifier in SO-14 — four independent internally frequency-compensated op amps, 1.3 MHz gain-bandwidth product, 0.5 V/µs slew rate, 7 mV maximum input offset, single 3 V to 32 V or dual ±1.5 V to ±16 V supply, common-mode input range including ground, tape-and-reel packing (T), 0 to +70 °C. The four-amplifier single-supply integration is the selection point: the industry-standard quad for 5 V systems — comparators, filters, summers and transducer amplifiers in one SO-14 package with supply current independent of supply voltage. Selection advice: the DT code is the SO-14 reel version — the N code is DIP-14 and PT is TSSOP-14, so match the full LM324DT code for package and packing. Not rail-to-rail; allow headroom on both rails. Evidence: ST LM324 datasheet and distributor listings confirm quad, 1.3 MHz, SO-14, reel packing and 0-70 °C. Match the full LM324DT code.

CD4066BE is a Texas Instruments quad bilateral analog switch — 4 × SPST, 14-pin PDIP-14 (N), 3–18 V supply, −55 to +125 °C. The wide supply range is the selection point: it switches analog and digital signals from 3 V logic rails up to 18 V systems — the classic CMOS switch for signal routing and multiplexing. Selection advice: TI lists the CD4066BE as Active. Note the ~125 Ω typical on-resistance — for precision analog paths verify the resistance flatness and voltage dependence against your error budget; for lower on-resistance use a modern analog switch family instead. The BE suffix denotes PDIP-14 — the same die ships in SOIC under different suffixes, so match the package code to your footprint. Evidence: TI data confirms Active, quad SPST, PDIP-14, 3–18 V. Match the full CD4066BE code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Texas Instruments lists LM339N as ACTIVE — a quad differential comparator in 14-pin PDIP-14 (N), up to 38 V supply, 1 µs response, 0.37 mV input offset, 0 to 70 °C. Four comparators in one package is the procurement advantage: window detectors, zero-crossing detection and multi-channel threshold monitoring from a single device. Selection advice: the N suffix denotes PDIP-14 — the LM339 ships in SOIC and other packages, so match the full LM339N code. Like the LM393, these are open-collector outputs for wired-OR and level translation; confirm your circuit needs comparators rather than op-amps before substituting. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Texas Instruments lists ADS1115IDGSR as an ACTIVE 16-bit delta-sigma ADC in VSSOP-10, with 860 SPS sampling, 4 multiplexed channels and I2C interface. The 16-bit resolution is the procurement-relevant advantage: it resolves small sensor signals that a 10- or 12-bit converter would bury in quantization noise, which is why this part is the default choice for precision data-acquisition front ends. Selection advice: the IDGSR suffix pins the VSSOP-10 package on tape and reel — the ADS1115 also ships in other packages, so match the full code to your layout. Four multiplexed inputs versus the two-channel ADS1113 and single-ended/differential options are the family decision points; confirm your channel count and interface (I2C here, not SPI) against the datasheet before substituting. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADS1115IDGST is a Texas Instruments ADS1115 16-bit delta-sigma analog-to-digital converter — four single-ended or two differential inputs, programmable gain amplifier with full-scale ranges from ±6.144 V down to ±0.256 V, programmable data rates from 8 to 860 SPS, I2C interface with four pin-selectable addresses, in 10-pin VSSOP, tube packing (DGST), -40 to +125 °C. The integrated PGA, low-drift reference and oscillator are the selection point: true precision ADC performance with no external reference or clock, ideal for battery-voltage monitoring, temperature measurement and portable instrumentation. Selection advice: 860 SPS suits slow precision signals — for kilohertz sampling choose an SAR ADC (ADS868x family) instead. The built-in comparator can drive an alert pin for threshold monitoring without MCU polling, and 16 I2C addresses (four pins × four states) let you run multiple converters on one bus. Note this exact ADS1115IDGST code is the tube variant; IDGSR is the reel version. Evidence: TI ADS1115 datasheet (SBAS444D) and distributor listings confirm 16-bit, PGA ranges, 8-860 SPS, VSSOP-10 and tube packing. Match the full ADS1115IDGST code for packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADS1115IDYNR is a Texas Instruments ADS1115 16-bit delta-sigma analog-to-digital converter in the 10-pin SOT-23 package — four single-ended or two differential inputs, programmable gain from ±6.144 V to ±0.256 V full-scale, 8 to 860 SPS, I2C with four pin-selectable addresses, tape-and-reel packing (DYNR), -40 to +125 °C. The SOT-23 footprint is the selection point: full 16-bit precision with PGA, internal reference and comparator in the smallest ADS1115 package for space-constrained sensor nodes. Selection advice: same die and performance as the VSSOP (IDGST) and X2QFN (IRUGR) variants — choose this code for the SOT-23 footprint and reel packing. The 150 µA active current and single-shot power-down mode suit battery designs; for 24-bit resolution or excitation sources step up to the ADS1220. TI lists this code as Active. Evidence: TI ADS1115 datasheet (SBAS444D) and distributor listings confirm 16-bit, PGA, I2C, SOT-23-10 and reel packing. Match the full ADS1115IDYNR code for package and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADS1115IRUGR is a Texas Instruments ADS1115 16-bit delta-sigma analog-to-digital converter in the 10-pin X2QFN package (2 × 1.5 × 0.4 mm) — four single-ended or two differential inputs, programmable gain from ±6.144 V to ±0.256 V full-scale, 8 to 860 SPS, I2C with four pin-selectable addresses, tape-and-reel packing of 3000 (IRUGR; IRUGT is the small reel), -40 to +125 °C. The 2 × 1.5 mm footprint is the selection point: full 16-bit precision with PGA, internal reference and comparator in one of the smallest ADC packages available, for wearables and dense sensor boards. Selection advice: same die and performance as the VSSOP (IDGSR) and SOT-23 (IDYNR) variants — choose this code for the X2QFN footprint and 3000-reel packing. Leadless QFN needs reflow assembly and good layout practice; for hand-soldering prototypes choose the VSSOP variant. TI lists this code as Active. Evidence: TI ADS1115 datasheet (SBAS444D), TI pack addendum and DigiKey listings confirm 16-bit, PGA, I2C, X2QFN-10 and 3000-reel packing. Match the full ADS1115IRUGR code for package and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADS1115IRUGT is a Texas Instruments 16-bit delta-sigma ADC in 10-pin X2QFN (2.0 × 1.5 × 0.4 mm), 250-piece small reel — I2C interface, four single-ended or two differential inputs, programmable gain amplifier (±256 mV to ±6.144 V), internal low-drift reference and oscillator, programmable comparator, 8 to 860 SPS, 2.0–5.5 V, 150 µA, −40 °C to +125 °C. The integration is the selection point: PGA, MUX, reference, oscillator and comparator on one 2×1.5 mm die means a complete sensor front end with no external analog support chips. Selection advice: the RUG package code is the X2QFN — ADS1115IDGST is the same die in VSSOP-10 on 250-piece small reel — the easier-to-assemble alternative for designs that do not need the 2×1.5 mm X2QFN footprint, not interchangeable on the same footprint. Against the 12-bit ADS1015: pick the ADS1115 for resolution (weighing, precision sensing), the ADS1015 for speed (3300 SPS). The ADDR pin gives four I2C addresses, so up to four devices share one bus. Evidence: TI ADS1115 datasheet (ordering addendum) and distributor listings confirm X2QFN-10, 250-reel, 16-bit, I2C and −40 to +125 °C. Match the full ADS1115IRUGT code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADS1220IPW is a Texas Instruments ADS1220 24-bit delta-sigma analog-to-digital converter for small-signal sensors — programmable gain from 1 to 128 V/V, up to 2000 SPS with single-cycle settling, SPI-compatible interface, in 16-pin TSSOP, tube packing (IPW; IPWR is the reel version), -40 to +125 °C. The two programmable excitation current sources plus simultaneous 50/60 Hz rejection at 20 SPS are the selection point: complete RTD, thermocouple, bridge-sensor and weigh-scale front ends with no external current source or mains-noise filtering. Selection advice: 20-bit effective resolution suits precision instrumentation — for kilohertz sampling choose an SAR ADC instead. The internal 2.048 V reference, oscillator and temperature sensor cut the external BOM to near zero; for I2C instead of SPI choose the ADS1115 family. TI lists this code as Active. Evidence: TI ADS1220 datasheet (SBAS501D) and TI pack addendum confirm 24-bit, PGA 1-128, 2 kSPS, TSSOP-16 and tube packing. Match the full ADS1220IPW code for packing.
