## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of channel A; the output swings rail-to-rail and is diode-clamped to the supply rails, with output currents limited to ±100 mA for signals beyond 0.2 V outside the rails. |
| 2 | -INA | input | Inverting input of channel A; signals must stay within (V-)-0.2 V to (V+)+0.2 V, with input current limited to 10 mA if the signal swings more than 0.2 V beyond the rails. |
| 3 | +INA | input | Noninverting input of channel A; the common-mode input range extends from V- to 1.5 V below V+, and signals must stay within (V-)-0.2 V to (V+)+0.2 V. |
| 4 | V+ | power_in | Positive (highest) power supply; the supply range is 3 V to 32 V single-supply or ±1.5 V to ±16 V dual-supply, with absolute maximum (V+)-(V-) of 36 V. |
| 5 | +INB | input | Noninverting input of channel B; the common-mode input range extends from V- to 1.5 V below V+, and signals must stay within (V-)-0.2 V to (V+)+0.2 V. |
| 6 | -INB | input | Inverting input of channel B; signals must stay within (V-)-0.2 V to (V+)+0.2 V, with input current limited to 10 mA if the signal swings more than 0.2 V beyond the rails. |
| 7 | OUTB | output | Output of channel B; the output swings rail-to-rail and is diode-clamped to the supply rails, with output currents limited to ±100 mA for signals beyond 0.2 V outside the rails. |
| 8 | OUTC | output | Output of channel C; the output swings rail-to-rail and is diode-clamped to the supply rails, with output currents limited to ±100 mA for signals beyond 0.2 V outside the rails. |
| 9 | -INC | input | Inverting input of channel C; signals must stay within (V-)-0.2 V to (V+)+0.2 V, with input current limited to 10 mA if the signal swings more than 0.2 V beyond the rails. |
| 10 | +INC | input | Noninverting input of channel C; the common-mode input range extends from V- to 1.5 V below V+, and signals must stay within (V-)-0.2 V to (V+)+0.2 V. |
| 11 | V- | power_in | Negative (lowest) power supply or ground for single-supply operation; the supply range is referenced to this pin. |
| 12 | +IND | input | Noninverting input of channel D; the common-mode input range extends from V- to 1.5 V below V+, and signals must stay within (V-)-0.2 V to (V+)+0.2 V. |
| 13 | -IND | input | Inverting input of channel D; signals must stay within (V-)-0.2 V to (V+)+0.2 V, with input current limited to 10 mA if the signal swings more than 0.2 V beyond the rails. |
| 14 | OUTD | output | Output of channel D; the output swings rail-to-rail and is diode-clamped to the supply rails, with output currents limited to ±100 mA for signals beyond 0.2 V outside the rails. |
