## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VO1 | output | Amplifier 1 output pin. Rail-to-rail output stage capable of sourcing/sinking up to 75 mA (typical) linear output current. |
| 2 | VIN1- | input | Amplifier 1 inverting input pin. FET input stage with 2 pA typical input bias current; rail-to-rail input range. |
| 3 | VIN1+ | input | Amplifier 1 noninverting input pin. FET input stage with 2 pA typical input bias current; rail-to-rail input range. |
| 4 | VS- | power_in | Negative power supply pin. Total supply voltage (VS+ − VS−) from 4.75 V to 27 V; typically −5 V for ±5 V split-supply operation. |
| 5 | VIN2+ | input | Amplifier 2 noninverting input pin. FET input stage with 2 pA typical input bias current; rail-to-rail input range. |
| 6 | VIN2- | input | Amplifier 2 inverting input pin. FET input stage with 2 pA typical input bias current; rail-to-rail input range. |
| 7 | VO2 | output | Amplifier 2 output pin. Rail-to-rail output stage capable of sourcing/sinking up to 75 mA (typical) linear output current. |
| 8 | VS+ | power_in | Positive power supply pin. Total supply voltage (VS+ − VS−) from 4.75 V to 27 V; typically +5 V for ±5 V split-supply operation. Quiescent current 3.6 mA per channel (typical). |
