OPA2134PA

NE5532D is a Texas Instruments dual audio op amp — 30 V max supply, 10 MHz gain-bandwidth, 9 V/µs slew rate, 5 nV/√Hz noise, 8-SOIC, tube, 0 to +70 °C. The low-noise audio performance is the selection point: the classic dual op amp for preamps, mixers and active filters — a reference design part for decades. Selection advice: lifecycle warning — distributors list the NE5532D as Obsolete; for repairs and legacy audio builds we source remaining tube stock, and for new designs qualify a current-production low-noise op amp. The D suffix denotes SOIC-8 on tube — match it to your assembly process, since reel codes differ. Evidence: DigiKey confirms Obsolete status, 8-SOIC, tube; TI data confirms 10 MHz GBW, 9 V/µs, 5 nV/√Hz. Match the full NE5532D code.

OPA1612AID is a Texas Instruments SoundPlus dual audio operational amplifier in 8-pin SOIC — the reference bipolar audio op-amp for pro-audio and high-end consumer gear: mixing consoles, audio interfaces and phono stages. 1.1 nV/√Hz noise at 1 kHz, 0.000015% THD+N, 40 MHz gain bandwidth and 27 V/µs slew rate, on ±2.25 V to ±18 V at 3.6 mA per channel. The bipolar input stage is the selection point over CMOS alternatives: lowest voltage noise with low source impedances, which is exactly what moving-coil and low-impedance DAC outputs present. Selection advice: the AID code is the tube SOIC for builds and repairs — AIDR is the 2500-reel for production; for new FET-input designs compare the OPA1656 on this site. Beware remarked parts on the open market — this is one of the most counterfeited audio op-amps, so require lot traceability. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

OPA1656IDR is a Texas Instruments Burr-Brown dual audio operational amplifier in 8-pin SOIC — for premium audio signal chains where noise and distortion define the product tier: DAC output stages, microphone preamps and headphone drivers. 2.9 nV/√Hz voltage noise, -131 dB THD+N at 1 kHz, 53 MHz gain-bandwidth product and 24 V/µs slew rate, on ±2.25 V to ±18 V supplies at 3.9 mA per channel. The CMOS FET input draws only 10 pA bias current, so high-impedance sources see no loading error. Selection advice: this is the modern CMOS successor path from the bipolar OPA1612 on this site — pick the OPA1656 when the design needs FET inputs or lower supply current; stay with the OPA1612 for the absolute lowest bipolar noise. The IDR code is the 2500-reel SOIC — ID is the tube for prototypes. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LM358P is a Texas Instruments LM358 dual operational amplifier in PDIP-8, tube packaging — single supply 3 V to 32 V (or ±1.5 V to ±16 V dual), input common-mode range includes ground, unity-gain stable, two independent op-amps on one die. The PDIP-8 package is the selection point: through-hole for breadboards, teaching labs, prototyping and legacy repairs — the same LM358 die ships in SOIC, TSSOP and VSSOP under different suffixes, so match the full LM358P code to your board. Selection advice: the ground-sensing input of the LM358 is why it survives in single-supply sensor front ends where older op-amps cannot swing low enough — pick it for comparators, active filters and transducer amplifiers on a single rail. It is not rail-to-rail output and not precision (millivolt offsets), so for low-voltage precision work step up to a modern RRIO part. As the most remarked jellybean op-amp in the market, require lot traceability. Evidence: TI LM358 product page confirms PDIP-8, 3–32 V single supply and ground-sensing inputs. Match the full LM358P code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LM393P is a Texas Instruments dual differential voltage comparator in 8-pin PDIP, tube packaging — open-collector outputs, 1.3 µs typical response time, 2 V to 36 V single-supply (or ±1 V to ±18 V dual) operation, common-mode input range that includes ground, 0 to +70 °C (P = PDIP commercial grade). The open-collector outputs with a ground-including input range are the selection point: it runs from a single 5 V rail while sensing signals down to ground, and the outputs wire-OR together for window detectors, level shifters and zero-crossing detectors in limit monitoring, battery supervisors and fan controllers. Selection advice: the P suffix is the PDIP-8 tube version — the same die ships as LM393D/DR (SOIC) for SMD lines; and because it is a comparator rather than an op amp, do not substitute an LM358 here — dedicated comparators switch far faster under saturated conditions and tolerate the high differential input voltages that would latch an op amp. TI lists LM393P as Active. Evidence: TI LM393/LM2903 datasheet and distributor listings confirm dual channels, open-collector, 1.3 µs, 2–36 V, PDIP-8 and tube packing. Match the full LM393P 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 NE5532P as an ACTIVE dual low-noise operational amplifier for audio applications in PDIP-8, with 10 MHz gain bandwidth, 9 V/µs slew rate and 10 V to 30 V supply range. The low-noise bipolar input stage is the selection point: it became the reference audio op-amp for mixing consoles and phono stages, and remains the benchmark newer audio op-amps are compared against. Selection advice: the P suffix denotes PDIP-8 — the NE5532 also ships in SOIC-8, so match the full NE5532P code to your footprint. For the lowest distortion, compare against the FET-input OPA2134; for the classic low-noise bipolar sound, match this code exactly. 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 TL072CP as a dual JFET-input operational amplifier in PDIP-8 — for high-input-impedance analog signal paths such as guitar preamps, piezo buffers and electrometer front ends. The JFET input stage is the selection point: picoamp-level input bias current that bipolar op-amps cannot match, which is why the TL072 dominated audio and sensor front ends for decades. Selection advice: the CP suffix denotes PDIP-8 in tube packaging — the TL072 also ships in SOIC-8, so match the full TL072CP code to your footprint and packing needs. For lower noise, compare against the NE5532; for the classic JFET-input behavior, match this code exactly. 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.

TL072IP is a Texas Instruments TL072 dual JFET-input operational amplifier in PDIP-8, tube packaging — 3 MHz gain-bandwidth, 13 V per microsecond slew rate, JFET inputs with picoamp bias current, common-mode range includes VCC+, 1.4 mA per channel, industrial −40 °C to +85 °C grade. The IP code is the selection point: the industrial-grade die in through-hole PDIP-8 — the prototyping, teaching-lab and repair choice, socketable and hand-solderable, with the wider temperature range the commercial CP codes lack. Selection advice: pick the IP for breadboards, one-offs and field repairs; pick the IDR (SOIC-8 reel) or CPWR (TSSOP-8 reel) for production — same die, different assembly flow. The JFET input keeps bias-current errors negligible on high-impedance audio and sensor sources. Not rail-to-rail output. Evidence: TI TL072 datasheet ordering information and distributor listings confirm PDIP-8 (P), tube packaging and the I-grade −40 to +85 °C range. Match the full TL072IP 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 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.
