Short-circuit protected; typical short-circuit current ±24 mA at VCC=5V, VEE=-5V. |+| 2 | 1IN- | input | Inverting input of op-amp channel 1. Input bias current typically 50 nA, common-mode range VEE to VCC-1.5V. |+| 3 | 1IN+ | input | Non-inverting input of op-amp channel 1. Input bias current typically 50 nA, common-mode range VEE to VCC-1.5V. |+| 4 | VEE | power_in | Negative supply / ground pin. Tie to GND for single-supply operation (VCC 3V to 36V) or to negative rail for split-supply operation (up to ±18V). |+| 5 | 2IN+ | input | Non-inverting input of op-amp channel 2. Input bias current typically 50 nA, common-mode range VEE to VCC-1.5V. |+| 6 | 2IN- | input | Inverting input of op-amp channel 2.
