## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTPUT 1 | output | Output of op-amp channel 1. Can sink/source current with typical short-circuit output current of 40mA at VCC=15V; output voltage swing ranges from ~0V (VOL ~5mV typ at RL=10kΩ, VCC=5V) up to VCC-1.5V. |
| 2 | INPUT 1- | input | Inverting input of op-amp channel 1. Input bias current is 20nA typical, input offset current 5nA typical. Input common-mode range includes ground (0V to VCC-1.5V). |
| 3 | INPUT 1+ | input | Non-inverting input of op-amp channel 1. Input bias current 20nA typical; input common-mode range includes ground (0V to VCC-1.5V). Either input can tolerate up to +36V independent of VCC magnitude. |
| 4 | GND | power_in | Ground / negative supply rail. For single-supply operation, tie to 0V; for split-supply operation, connect to the negative rail (down to -18V relative to VCC). |
| 5 | INPUT 2+ | input | Non-inverting input of op-amp channel 2. Input bias current 20nA typical; input common-mode range includes ground (0V to VCC-1.5V). |
| 6 | INPUT 2- | input | Inverting input of op-amp channel 2. Input bias current 20nA typical, input offset current 5nA typical. |
| 7 | OUTPUT 2 | output | Output of op-amp channel 2. Output voltage swing from ~0V to VCC-1.5V; typical short-circuit output current 40mA at VCC=15V. |
| 8 | VCC | power_in | Positive power supply. Single-supply range: 3V to 36V; split-supply range: ±1.5V to ±18V. Absolute maximum 40V. Supply current 0.5mA typical at VCC=5V. |
