## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. |
| 2 | -IN | input | Inverting input terminal with maximum signal voltage (V-) - 0.5 to (V+) + 0.5 V and input current limit ±10 mA. |
| 3 | +IN | input | Noninverting input terminal with maximum signal voltage (V-) - 0.5 to (V+) + 0.5 V and input current limit ±10 mA. |
| 4 | V- | power_in | Negative power supply with operating voltage ±2.25 to ±18 V (bipolar-supply) or ground reference (single-supply). |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Output terminal with rail-to-rail swing within 18 mV of supply rails and continuous short-circuit capability. |
| 7 | V+ | power_in | Positive power supply with operating voltage 4.5 to 36 V (single-supply) or ±2.25 to ±18 V (bipolar-supply). |
| 8 | NC | unconnected | No internal connection. |
