LM2903AVQDRQ1

Texas Instruments · Comparators · SOIC-8

LM2903AVQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Open-collector output of comparator 1. Requires an external pull-up resistor to a positive supply (typically 3 V to 36 V). Can sink >6 mA; may be wire-OR'd with 2OUT.
2 1IN- input Inverting input of comparator 1. Common-mode input range includes ground (V- to V+ - 1.5 V). Differential input voltage rated to the supply voltage.
3 1IN+ input Non-inverting input of comparator 1. Common-mode input range includes ground (V- to V+ - 1.5 V).
4 GND power_in Ground / negative supply pin (V-). Connect to system ground for single-supply operation, or to the negative rail for split-supply (±1.5 V to ±18 V) operation.
5 2IN+ input Non-inverting input of comparator 2. Common-mode input range includes ground (V- to V+ - 1.5 V).
6 2IN- input Inverting input of comparator 2. Common-mode input range includes ground (V- to V+ - 1.5 V).
7 2OUT output Open-collector output of comparator 2. Requires an external pull-up resistor to a positive supply. Can sink >6 mA; may be wire-OR'd with 1OUT.
8 VCC power_in Positive supply pin (V+). Single-supply operation: 3 V to 36 V. Split-supply operation: +1.5 V to +18 V. Absolute maximum 36 V single or ±18 V split.

CAD (KiCad official)

  • Symbol: LM2903AVQDRQ1
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm2903avqdrq1-etched.step / lm2903avqdrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2903avqdrq1.step / lm2903avqdrq1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2903avqdrq1.step 122 KB You want the bare part, or you mark your own boards.
lm2903avqdrq1-etched.step 2.6 MB You want the part with LM2903AVQDRQ1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 632 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (21 pp, sha256 b0fe02e974eddf25, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
