## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of op-amp channel A. Rail-to-rail output stage swings within a few mV of both supply rails; short-circuit current limit typ. 48mA at Vs=+5V. |
| 2 | -INA | input | Inverting input of op-amp channel A. Rail-to-rail input; input bias current typ. 10pA, input offset current typ. 5pA. |
| 3 | +INA | input | Non-inverting input of op-amp channel A. Rail-to-rail input range 0V to +Vs; input bias current typ. 10pA. |
| 4 | -Vs | power_in | Negative supply / ground pin. In single-supply operation connect to GND; total supply voltage +Vs to -Vs must be between 2.5V and 5.5V (absolute max 6V). |
| 5 | +INB | input | Non-inverting input of op-amp channel B. Rail-to-rail input range 0V to +Vs; input bias current typ. 10pA. |
| 6 | -INB | input | Inverting input of op-amp channel B. Rail-to-rail input; input bias current typ. 10pA, input offset current typ. 5pA. |
| 7 | OUTB | output | Output of op-amp channel B. Rail-to-rail output stage; short-circuit current limit typ. 48mA at Vs=+5V. |
| 8 | +Vs | power_in | Positive supply pin. Operating range 2.5V to 5.5V referenced to -Vs; absolute maximum 6V. Total quiescent current typ. 930µA at Vs=+5V (both channels). |
