LM2903AVQPWR

Texas Instruments · Comparators · TSSOP-8

LM2903AVQPWR from Texas Instruments, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Output of comparator 1, an open-drain NPN pull-down output that sinks current when IN- is above IN+ plus the offset voltage, so it needs an external pull-up.
2 1IN- input Inverting input of comparator 1.
3 1IN+ input Non-inverting input of comparator 1; for non-B-suffix devices the input common-mode range is 0 V to (V+) - 2.0 V.
4 GND power_in Ground reference pin for the device.
5 2IN+ input Non-inverting input of comparator 2.
6 2IN- input Inverting input of comparator 2.
7 2OUT output Output of comparator 2, an open-drain NPN pull-down output that needs an external pull-up.
8 VCC power_in Positive supply pin; the recommended supply for V-suffix devices such as LM2903AV is 2 V to 32 V, with an absolute maximum of 36 V for non-B devices.

CAD (KiCad official)

  • Symbol: LM2903AVQPWR
  • Footprint: Package_SO:TSSOP-8_3x3mm_P0.65mm
  • 3D model: TSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm2903avqpwr-etched.step / lm2903avqpwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2903avqpwr.step / lm2903avqpwr.glb are the bare package body.
