## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOS TRIM | passive | Offset adjust terminal; a 10k or 20k potentiometer between pins 1 and 8 gives about ±2.5mV of adjustment range without degrading drift. |
| 2 | -IN | input | Inverting input; differential input voltage is limited to ±30V and input voltage to ±22V (absolute maximum). |
| 3 | +IN | input | Non-inverting input; differential input voltage is limited to ±30V and input voltage to ±22V (absolute maximum). |
| 4 | V- | power_in | Negative supply; specified for ±3V to ±18V supplies, with an absolute maximum of ±22V. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Amplifier output; output short-circuit duration is indefinite, with voltage gain guaranteed at 10mA of load current. |
| 7 | V+ | power_in | Positive supply; specified for ±3V to ±18V supplies, with an absolute maximum of ±22V. |
| 8 | VOS TRIM | passive | Offset adjust terminal; a 10k or 20k potentiometer between pins 1 and 8 gives about ±2.5mV of adjustment range without degrading drift. |
