## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | Not connected on the D (SOIC-8) package; the datasheet specifies no function for this pin. |
| 2 | IN- | input | Inverting input; the input voltage must stay between (VCC-) + 4 V and (VCC+) + 0.1 V under recommended operating conditions for this device class. |
| 3 | IN+ | input | Non-inverting input; the input voltage must stay between (VCC-) + 4 V and (VCC+) + 0.1 V under recommended operating conditions for this device class. |
| 4 | VCC- | power_in | Negative power supply; the total supply VS = (VCC+) - (VCC-) must be 4.5 V to 40 V (±2.25 V to ±20 V). |
| 5 | NC | unconnected | Not connected on the D (SOIC-8) package; the datasheet specifies no function for this pin. |
| 6 | OUT | output | Amplifier output; a short circuit to ground is continuous, one amplifier per package, per the absolute maximum ratings. |
| 7 | VCC+ | power_in | Positive power supply; the total supply VS = (VCC+) - (VCC-) must be 4.5 V to 40 V (±2.25 V to ±20 V). |
| 8 | NC | unconnected | Not connected on the D (SOIC-8) package; the datasheet specifies no function for this pin. |
