Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Amplifier 1 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability. |
| 2 | IN1(-) | input | Amplifier 1 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 3 | IN1(+) | input | Amplifier 1 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 4 | VCC | power_in | Positive supply pin, operating range 3 V to 32 V single supply (or ±1.5 V to ±16 V split) with an absolute maximum of 32 V. |
| 5 | IN2(+) | input | Amplifier 2 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 6 | IN2(-) | input | Amplifier 2 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 7 | OUT2 | output | Amplifier 2 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability. |
| 8 | OUT3 | output | Amplifier 3 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability. |
| 9 | IN3(-) | input | Amplifier 3 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 10 | IN3(+) | input | Amplifier 3 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 11 | GND | power_in | Ground (negative supply) pin, which is the reference for the input and output voltage limits GND ≤ VIN or VOUT ≤ VCC. |
| 12 | IN4(+) | input | Amplifier 4 non-inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 13 | IN4(-) | input | Amplifier 4 inverting input, with common-mode range including ground and an absolute maximum input range of -0.3 V to 32 V. |
| 14 | OUT4 | output | Amplifier 4 output, with swing from 0 V to VCC-1.5 V and continuous short-circuit capability. |
