LM2903VQDR 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 | Comparator 1 open-drain output; low when 1IN- > 1IN+ plus input offset voltage. |
| 2 | 1IN- | input | Comparator 1 inverting input; common-mode voltage range GND to VCC-2.0 V. |
| 3 | 1IN+ | input | Comparator 1 non-inverting input; common-mode voltage range GND to VCC-2.0 V. |
| 4 | GND | power_in | Ground and negative supply reference for both comparators. |
| 5 | 2IN+ | input | Comparator 2 non-inverting input; common-mode voltage range GND to VCC-2.0 V. |
| 6 | 2IN- | input | Comparator 2 inverting input; common-mode voltage range GND to VCC-2.0 V. |
| 7 | 2OUT | output | Comparator 2 open-drain output; low when 2IN- > 2IN+ plus input offset voltage. |
| 8 | VCC | power_in | Positive power supply; 2-32 V operating range for LM2903V variant. |
