## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of op amp A, which has rail-to-rail output swing. |
| 2 | -IN A | input | Inverting input of op amp A; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 3 | +IN A | input | Non-inverting input of op amp A; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 4 | V+ | power_in | Positive supply, specified from +2.7V to +5.5V with respect to V-; supply voltages above 7V (absolute maximum) can permanently damage the amplifier. |
| 5 | +IN B | input | Non-inverting input of op amp B; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 6 | -IN B | input | Inverting input of op amp B; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 7 | OUT B | output | Output of op amp B, which has rail-to-rail output swing. |
| 8 | OUT C | output | Output of op amp C, which has rail-to-rail output swing. |
| 9 | -IN C | input | Inverting input of op amp C; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 10 | +IN C | input | Non-inverting input of op amp C; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 11 | V- | power_in | Negative supply rail (single-supply operation uses this pin as ground); the amplifier operates from +2.7V to +5.5V between V+ and V-. |
| 12 | +IN D | input | Non-inverting input of op amp D; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 13 | -IN D | input | Inverting input of op amp D; common-mode range is (V-) - 0.1V to (V+) + 0.1V, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA. |
| 14 | OUT D | output | Output of op amp D, which has rail-to-rail output swing. |
