Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Output 1 | output | Output of op-amp 1; output short-circuit to ground is tolerated, with output current limited to about 40mA independent of VCC. |
| 2 | Inverting Input 1 | input | Inverting input of op-amp 1; input current is limited to 50mA maximum and the input should not be driven below -0.3V for normal output operation. |
| 3 | Non-inverting Input 1 | input | Non-inverting input of op-amp 1; common-mode range extends from ground up to VCC+ -1.5V, and it can go to +32V without damage. |
| 4 | VCC+ | power_in | Positive supply pin; single supply +3V to +30V or dual supplies ±1.5V to ±15V. |
| 5 | Non-inverting Input 2 | input | Non-inverting input of op-amp 2; common-mode range extends from ground up to VCC+ -1.5V, and it can go to +32V without damage. |
| 6 | Inverting Input 2 | input | Inverting input of op-amp 2; input current is limited to 50mA maximum and the input should not be driven below -0.3V for normal output operation. |
| 7 | Output 2 | output | Output of op-amp 2; output short-circuit to ground is tolerated, with output current limited to about 40mA independent of VCC. |
| 8 | Output 3 | output | Output of op-amp 3; output short-circuit to ground is tolerated, with output current limited to about 40mA independent of VCC. |
| 9 | Inverting Input 3 | input | Inverting input of op-amp 3; input current is limited to 50mA maximum and the input should not be driven below -0.3V for normal output operation. |
| 10 | Non-inverting Input 3 | input | Non-inverting input of op-amp 3; common-mode range extends from ground up to VCC+ -1.5V, and it can go to +32V without damage. |
| 11 | VCC-/GND | power_in | Negative supply pin, ground in single-supply operation (Vcc- = ground in test conditions); inputs must not go negative by more than 0.3V. |
| 12 | Non-inverting Input 4 | input | Non-inverting input of op-amp 4; common-mode range extends from ground up to VCC+ -1.5V, and it can go to +32V without damage. |
| 13 | Inverting Input 4 | input | Inverting input of op-amp 4; input current is limited to 50mA maximum and the input should not be driven below -0.3V for normal output operation. |
| 14 | Output 4 | output | Output of op-amp 4; output short-circuit to ground is tolerated, with output current limited to about 40mA independent of VCC. |
