LF351DT from STMicroelectronics, in a SO-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 | Offset null 1 | passive | Offset null 1 input; used with offset null 2 and external potentiometer for input offset voltage trimming. |
| 2 | Inverting input | input | Inverting input terminal; input voltage limited to ±15V with respect to ground. |
| 3 | Non-inverting input | input | Non-inverting input terminal; input voltage limited to ±15V with respect to ground. |
| 4 | VCC− | power_in | Negative supply voltage terminal; rated ±18V absolute maximum. |
| 5 | Offset null 2 | passive | Offset null 2 input; used with offset null 1 and external potentiometer for input offset voltage trimming. |
| 6 | Output | output | Output terminal; short-circuit to ground or either supply voltage permitted indefinitely per absolute maximum ratings. |
| 7 | VCC+ | power_in | Positive supply voltage terminal; rated ±18V absolute maximum. |
| 8 | N.C. | unconnected | Not connected; no internal connection. |
