## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Op-amp channel 1 output. Ground-sense output capable of swinging down to VEE; sources up to 30mA typ / sinks up to 20mA typ into loads referenced to VEE. Maximum output voltage high ≥3.5V with RL=2kΩ at VCC=5V. |
| 2 | -IN1 | input | Inverting input of op-amp channel 1. Input bias current 20nA typ (250nA max), input offset voltage 7mV max. Common-mode range 0V to (VCC-1.5V) with GND-sense capability. |
| 3 | +IN1 | input | Non-inverting input of op-amp channel 1. Input bias current 20nA typ (250nA max), input offset voltage 7mV max. Common-mode range 0V to (VCC-1.5V) with GND-sense capability. |
| 4 | VEE | power_in | Negative supply / ground pin. For single-supply operation connect to GND; for dual-supply operation connect to negative rail. VCC-VEE absolute maximum is +36V; operating range +3.0V to +36.0V. |
| 5 | +IN2 | input | Non-inverting input of op-amp channel 2. Input bias current 20nA typ (250nA max), input offset voltage 7mV max. Common-mode range 0V to (VCC-1.5V) with GND-sense capability. |
| 6 | -IN2 | input | Inverting input of op-amp channel 2. Input bias current 20nA typ (250nA max), input offset voltage 7mV max. Common-mode range 0V to (VCC-1.5V) with GND-sense capability. |
| 7 | OUT2 | output | Op-amp channel 2 output. Ground-sense output capable of swinging down to VEE; sources up to 30mA typ / sinks up to 20mA typ into loads referenced to VEE. Maximum output voltage high ≥3.5V with RL=2kΩ at VCC=5V. |
| 8 | VCC | power_in | Positive supply pin. Operating supply voltage +3.0V to +36.0V (single-supply); VCC-VEE absolute maximum +36V. Decouple to VEE with a local capacitor. |
