LM324A-SR from 3PEAK, in a SOIC-14. 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 | OUT A | output | Output of amplifier A, which swings rail-to-rail. |
| 2 | -IN A | input | Inverting input of amplifier A; the input common-mode range extends to V- (ground). |
| 3 | +IN A | input | Non-inverting input of amplifier A; the input common-mode range extends to V- (ground). |
| 4 | +VS | power_in | Positive supply, specified from 3V to 36V (absolute maximum supply 40V). |
| 5 | +IN B | input | Non-inverting input of amplifier B; the input common-mode range extends to V- (ground). |
| 6 | -IN B | input | Inverting input of amplifier B; the input common-mode range extends to V- (ground). |
| 7 | OUT B | output | Output of amplifier B, which swings rail-to-rail. |
| 8 | OUT C | output | Output of amplifier C, which swings rail-to-rail. |
| 9 | -IN C | input | Inverting input of amplifier C; the input common-mode range extends to V- (ground). |
| 10 | +IN C | input | Non-inverting input of amplifier C; the input common-mode range extends to V- (ground). |
| 11 | -VS | power_in | Negative supply (V-), typically ground; the input common-mode range extends to this pin. |
| 12 | +IN D | input | Non-inverting input of amplifier D; the input common-mode range extends to V- (ground). |
| 13 | -IN D | input | Inverting input of amplifier D; the input common-mode range extends to V- (ground). |
| 14 | OUT D | output | Output of amplifier D, which swings rail-to-rail. |
