LM293DR

NCV2903DR2G is an onsemi AEC-Q100 qualified dual comparator in SOIC-8, tape and reel — the automotive-grade version of the classic LM2903/LM393 architecture. 2 V to 36 V single-supply (or ±1 V to ±18 V dual) operation with open-collector outputs, 1.3 µs propagation delay, 250 nA input bias current, 7 mV offset and −40 °C to +125 °C temperature range. The automotive qualification is the selection point: the same threshold-detection, zero-crossing and oscillator circuits engineers already know from the LM393, but rated and qualified for under-hood and body electronics where a commercial comparator cannot go. Selection advice: the NCV prefix is the automotive line — for pin-compatible commercial designs use the LM393/LM2903 family; DR2G denotes SOIC-8 tape and reel (2500/reel). Open-collector outputs need pull-up resistors and can be wire-ORed across channels. Evidence: Mouser, DigiKey and Future Electronics listings confirm 2–36 V, dual open-collector, AEC-Q100, SOIC-8 and Active status.

AMC1350DWVR is a Texas Instruments isolated amplifier in 8-pin SOIC — for precision voltage sensing across isolation barriers: reinforced isolation with ±5V input range, optimized for AC voltage measurement in motor drives, solar inverters and power supplies where the high-voltage side must be galvanically separated from the control side. The DWVR code is the SOIC-8 reel variant with 1000-unit reel. Selection advice: the AMC1350 targets AC voltage sensing (±5V input) — for DC shunt-based current sensing the AMC1301 family is the companion choice; for designs needing an integrated DC/DC converter to power the high side, the AMC3330 eliminates the external isolated supply. Against non-isolated precision amps on this site, the isolation barrier is the differentiator — do not substitute a non-isolated amp where safety isolation is required. Heat evidence: listed in Octopart Linear ICs Popular Parts (octopart.com, verified 2026-10-09); TI E2E forum shows active customer evaluation for high-voltage measurement. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TI lists INA219AID as OBSOLETE — a 26 V, 12-bit I2C digital power monitor in 8-pin SOIC-8 (D) tube, for bidirectional current and power measurement with 0–26 V common-mode range and programmable gain. Important for procurement: only this tube-packing ordering code is obsolete — TI confirms the tape-and-reel variant INA219AIDR remains active, so if your assembly can take reel packing, qualify INA219AIDR as the drop-in replacement rather than chasing obsolete tube stock. Selection advice: for repairs and last-time builds of the AID code, send quantity and date-code requirements with your RFQ and we will check what can still be sourced with traceability; for new designs, specify INA219AIDR or a current-generation power monitor. Parameters verified against the TI official product page. We reconfirm the offered lot before quotation and reply within 24 hours.

Texas Instruments lists INA219AIDR as an ACTIVE digital current and power monitor in SOIC-8 — for I2C-based power measurements with 0–26 V common-mode range, 12-bit resolution and programmable gain. The digital I2C output is the selection point: current, voltage and computed power read directly by the host MCU, no analog signal chain needed. Selection advice: the AIDR suffix denotes SOIC-8 on tape and reel — the tube-packing INA219AID code is obsolete, so for production specify INA219AIDR. Confirm your shunt resistor value and current range against the datasheet before committing. 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.

INA219BIDR is a Texas Instruments B-grade zero-drift bidirectional current/power monitor in SOIC-8, 3000-piece large reel — 0.5% maximum accuracy over temperature (B grade), 0–26 V bus sensing, 3–5.5 V supply, 12-bit ADC with programmable averaging to 128 samples, calibration register for direct ampere and watt readouts, 16 programmable I2C addresses, −40 °C to +125 °C. The SOIC-8 package is the selection point: the same B-grade 0.5% die as the SOT-23 variants, but in a package that hand-solders and reworks comfortably — a real advantage for repair, rework and low-cost assembly flows. Selection advice: the D code is SOIC-8 — not footprint-compatible with the SOT-23-8 INA219BIDCNR/IDCNT, so pick the package before the PCB is taped out. The R suffix is the 3000-piece reel for volume; for small runs the SOT-23 T-reel variant is the economical prototype path. Evidence: TI INA219 datasheet (Rev. G) confirms B-grade 0.5%, SOIC-8 and the 3000-reel option. Match the full INA219BIDR code.

The INA240A1EDRQ1 is an AEC-Q100 automotive bidirectional current-sense amplifier in 8-pin SOIC. It senses shunt drops over a -4 V to 80 V common-mode range independent of supply voltage, so it handles high-side, low-side and below-ground flyback transients in motor drives and solenoid controls. Enhanced PWM rejection suppresses large common-mode transients without output ripple, giving accurate current readings in PWM systems and cutting calibration and rework cost. Precision is guaranteed by +/-25 uV maximum offset, 250 nV per degC maximum offset drift, 0.2 percent maximum gain error and 2.5 ppm per degC maximum gain drift, with 132 dB DC CMRR and 400 kHz bandwidth. It runs from a single 2.7 V to 5.5 V supply at 2.4 mA maximum, is specified from -40C to +150C, and is functional safety-capable for ASIL system designs. Selection advice: the A1 suffix fixes gain at 20 V/V; if your ADC range calls for 50, 100 or 200 V/V, order the A2, A3 or A4 variants instead of resizing the shunt, because gain is factory-trimmed and not field adjustable.

LM2903DR is a Texas Instruments dual differential comparator in SOIC-8 — for industrial threshold detection: the extended-temperature sibling of the LM393. 2–30 V single supply (±1–15 V dual), 1.3 µs response, open-collector outputs, -40°C to +125°C operation. Heat evidence: the comparator market grows from $7.69B to $8.23B (2026 report) — the LM393/LM2903 family remains a permanent distributor staple with multi-thousand-piece stock. Selection advice: the DR suffix is SOIC-8 on reel — the LM2903 is the -40 to +125°C version of the LM393 (0 to 70°C); same footprint, do not mix temperature grades on automotive BOMs. Parameters verified against Texas Instruments documentation.

LM358DR is a dual general-purpose operational amplifier from Texas Instruments in an 8-pin SOIC package — for signal conditioning, active filters and comparator-with-hysteresis circuits. The single-supply operation down to 3 V is the selection point: it runs directly from the same rail as 3.3 V and 5 V logic, which is why the LM358 remains the default jelly-bean op-amp. Selection advice: the DR suffix denotes SOIC-8 on tape and reel — the LM358 ships in PDIP-8 and other packages, so match the full LM358DR code to your footprint. For new precision designs, compare against newer low-offset op-amps; for cost-driven general-purpose use, this is the part.

LMC555CMX/NOPB is a Texas Instruments LMC555 CMOS timer — the CMOS version of the industry-standard 555 — in 8-pin SOIC, tape-and-reel packing (X suffix), NOPB lead-free, 1.5 to 15 V supply, 3 MHz maximum astable frequency. Less than 1 mW typical dissipation at 5 V with far smaller supply-current spikes than the bipolar 555 is the selection point: precision timing that does not corrupt its own supply rail. Selection advice: choose the LMC555 over the bipolar NE555 when the design runs on batteries or low voltage (1.5 V operation is guaranteed), needs megahertz timing (3 MHz versus the bipolar part lower ceiling), or shares a supply with noise-sensitive analog stages. The datasheet states pin-for-pin compatibility with the 555 series, so it drops into existing 555 sockets electrically — but verify timing against the datasheet, since CMOS thresholds and drive levels differ from bipolar. Distributor listings place this ordering code at -40 to +85 °C. Evidence: TI LMC555 datasheet (SNAS558) and distributor listings confirm CMOS 555, 1.5-15 V, 3 MHz, SO-8 and reel packing. Match the full LMC555CMX/NOPB code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LMV358IDR is a Texas Instruments dual low-voltage operational amplifier in 8-pin SOIC — the 5 V-and-below workhorse for cost-sensitive signal conditioning: appliance controls, HVAC boards and portable instruments. 2.7 V to 5.5 V supply, 1 MHz gain bandwidth, rail-to-rail output swing, 210 µA typical supply current per channel, -40 to +125 °C operation. The low-voltage design is the selection point over the classic LM358: full specified performance at 3.3 V and 5 V single supplies where the LM358 is out of its comfort zone, with no crossover distortion. Selection advice: this is the low-voltage sibling of the LM358 on this site — pick the LMV358 for 3.3 V/5 V-only designs; keep the LM358 when the rail goes above 5.5 V or below ground sensing matters. The IDR code is the 2500-reel SOIC. Parameters verified against Texas Instruments documentation.
