## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Amplifier output. |
| 2 | -VS | power_in | Negative (lowest) power supply; the supply range is 1.7 V to 5.5 V across VS+ and VS-. |
| 3 | +IN | input | Non-inverting input of the amplifier; the common-mode range extends 100 mV beyond the supply rails (VS- - 0.1 V to VS+ + 0.1 V at 25 °C). |
| 4 | -IN | input | Inverting input of the amplifier; signal input current and voltage are limited to ±10 mA and VS- - 0.5 V to VS+ + 0.5 V. |
| 5 | +VS | power_in | Positive (highest) power supply; the absolute maximum supply voltage VS+ to VS- is 10.0 V. |
