LM393DT

Texas Instruments lists LM393DR as an ACTIVE dual differential comparator with open-collector outputs in SOIC-8, with 2 V to 36 V supply range. The open-collector output is the design-relevant detail: it allows wired-OR logic and level translation to a different supply rail with a single pull-up resistor, which push-pull comparators cannot do. Selection advice: the DR suffix denotes SOIC-8 on tape and reel — the LM393 ships in several packages, so match the full code to your footprint. A comparator is not an op-amp: confirm your circuit uses it for threshold detection rather than linear amplification before substituting. Parameters verified against the TI official product page.

LM358DT is an STMicroelectronics low-power dual operational amplifier in SOIC-8 — two independent internally frequency-compensated op amps, 1.1 MHz gain-bandwidth product, 0.6 V/µs slew rate, 7 mV maximum input offset, single 3 V to 32 V or dual ±1.5 V to ±15 V supply, common-mode input range including ground, tape-and-reel packing (T), 0 to +70 °C. The single-supply ground-sense input is the selection point: operation directly from a 5 V logic rail with the input range including ground — the reason it stays the default choice for transducer amplifiers, DC gain blocks and 5 V interface circuits. Selection advice: the DT code is the SOIC-8 reel version — the N code is DIP-8 and PT is TSSOP-8, so match the full LM358DT code for package and packing. It is not rail-to-rail; allow headroom on both rails in your design. Evidence: ST LM358 datasheet and distributor listings confirm dual, 1.1 MHz, SOIC-8, reel packing and 0-70 °C. Match the full LM358DT code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TSC240A1IPT is an STMicroelectronics high-precision bidirectional zero-drift current sense amplifier with enhanced PWM rejection — for shunt-based current measurement: -4V to +100V common-mode range independent of supply, fixed 20V/V gain, ±20µV maximum offset voltage, 150nV/°C offset drift (industry-lowest), 132dB DC CMRR, 0.20% maximum gain error, 2.7V to 5.5V supply, AEC-Q100 qualified, SO-8 package, -40°C to +125°C. The ultra-low drift lets designers use smaller shunt resistors without losing accuracy over temperature — lower sense voltage means less power wasted in the shunt; enhanced PWM rejection keeps measurements clean in fast-switching motor drives where ordinary amplifiers alias. Business impact: inline current sensing with this precision feeds better data into motor-control algorithms — torque ripple drops without a more expensive controller. Selection advice: the IPT code is the industrial SO-8 variant — for automotive grade check the A1IYPT; for different gains consider the TSC2020/TSC2021/TSC2022 family (x20/x50/x100). Featured on Mouser New Products (2026-10-13). Parameters verified against STMicroelectronics documentation.

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. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TDA7294HS is an STMicroelectronics TDA7294 100 V / 100 W DMOS audio power amplifier — class-AB mono, up to 100 W music power into 8 Ω, ±10 to ±40 V supply, in Multiwatt15H horizontal package, tube packing, 0 to +70 °C. The DMOS power stage with mute and standby is the selection point: Hi-Fi home-stereo and powered-speaker output stages with very low distortion, no switch on/off noise, and built-in short-circuit plus thermal protection. Selection advice: the HS suffix is the horizontal-leadform variant for heatsink mounting — confirm your mechanical layout matches Multiwatt15H, not the vertical TDA7294V. The tab connects to -Vs, so isolate or plan the heatsink accordingly. For stereo, use two devices; for lower power, the TDA7293 family offers pin-compatible options. Evidence: ST TDA7294 datasheet (DS0013) and Arrow/CPC listings confirm 100 W, ±40 V, Multiwatt15H, tube packing and Active status. Match the full TDA7294HS code for the horizontal package. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TDA7294V is a DMOS audio power amplifier from STMicroelectronics in a Multiwatt-15 package, for high-fidelity audio applications — Hi-Fi amplifiers, active speakers and car audio. Its advantage is the DMOS output stage: high output current with built-in thermal shutdown and short-circuit protection, which keeps a high-power audio design robust without elaborate discrete protection. Selection advice: the V suffix denotes the Multiwatt-15 vertical package — board mounting and heatsinking are integral to this part, so follow the datasheet mechanical and thermal guidance. High-power audio layouts are sensitive to grounding and supply decoupling; confirm your PCB follows the reference design. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TL431ACZ-AP is an STMicroelectronics programmable shunt voltage reference in TO-92, ammopack (AP, 2000 per pack) — 2.495 V typical reference with 1% initial accuracy (A grade), adjustable output from 2.5 V to 36 V via two external resistors, 1 mA to 100 mA cathode current range, 0.22 Ω typical dynamic impedance, 0 to +70 °C. The shunt-reference topology is the selection point: it behaves like a programmable Zener that sets its own reference voltage, so one part serves as a precision voltage reference, a comparator threshold, or the error amplifier in a flyback/forward SMPS feedback loop — the dominant use case for this industry-standard part. Selection advice: the code decodes as TL431 + A (1% accuracy) + C (0 to +70 °C) + Z (TO-92) + AP (ammopack) — match every character, because the B (0.4%) and I (−40 to +105 °C) variants and the SO-8/bulk packings are separate orderables. The 100 ppm/°C typical temperature coefficient makes it a reference for cost-sensitive loops, not for precision ADC references. ST lists TL431ACZ-AP as Active. Evidence: ST TL431 datasheet ordering table and distributor listings confirm 1% accuracy, 2.5–36 V, 1–100 mA, TO-92 and ammopack. Match the full TL431ACZ-AP code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AD4003BRMZ is an Analog Devices 18-bit, 2 MSPS successive-approximation ADC in 10-lead MSOP — for precision data acquisition that needs both speed and DC accuracy: automatic test equipment, portable instruments and machine automation. ±1 LSB maximum INL with 100.5 dB SNR and -123 dB THD at 1 kHz, no latency or pipeline delay with first conversion accurate, and a high-Z input mode plus long acquisition phase that lets low-power precision amplifiers drive it directly — no dedicated high-speed ADC driver required. Input span compression runs the driver and ADC from common rails without a negative supply. Selection advice: the BRMZ code is the MSOP-10 version — for 16-bit at lower cost the AD4000 is the family sibling; the 1.8 V single supply with 1.71–5.5 V logic interface suits battery-powered field instruments. Daisy-chainable SPI simplifies multichannel layouts. Parameters verified against Analog Devices documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AD5689RBRUZ is an Analog Devices dual 16-bit buffered voltage-output DAC in 16-lead TSSOP — for precision setpoint and calibration outputs in industrial control: PLC I/O cards, data acquisition and optical transceiver biasing. ±2 LSB maximum INL at 16 bits, an internal 2.5 V reference with 2 ppm/°C typical drift (no external reference needed), user-selectable gain of 1 or 2 for 2.5 V or 5 V full scale, 20 mA drive capability within 0.5 V of the rails, and 50 MHz SPI with daisy-chain and readback. Power-on reset to zero or midscale keeps outputs safe at startup. Selection advice: the BRUZ code is the TSSOP-16 tube version — for single-channel designs the AD5683R is the family sibling; against the octal DAC80508 on this site, the AD5689R is the pick for dual-channel precision nodes where per-channel accuracy matters more than channel count. The 4 µA power-down mode suits battery-backed calibration circuits. Parameters verified against Analog Devices documentation.

AD5761RARUZ is an Analog Devices 16-bit voltage-output DAC with integrated 2.5V reference in TSSOP-16 — for industrial automation outputs where one chip must cover every standard range: PLC analog outputs, servo control and process control. Eight software-programmable output ranges (0-5V, 0-10V, 0-20V, ±3V, ±5V, ±10V and more) with 5% overrange, a ±2ppm/°C drift reference and ±2-LSB maximum INL mean the output stays accurate without external trimming. Selection advice: the ARUZ code is the TSSOP-16 reel variant — for the smaller 3x3mm LFCSP specify the ACPZ; the AD5721R is the 12-bit cost-down sibling. Single-supply 4.75V-to-30V or dual-supply operation covers both unipolar and bipolar systems — confirm your supply configuration against the range table. Asynchronous LDAC and reset-to-zero/midscale suit safety-critical outputs. Parameters verified against Analog Devices documentation and distributor listings.
