## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT 1 | output | Output of amplifier 1. |
| 2 | IN 1- | input | Inverting input of amplifier 1; input voltage must not go more than -0.3V below GND. |
| 3 | IN 1+ | input | Non-inverting input of amplifier 1; common-mode range includes ground. |
| 4 | V+ | power_in | Positive supply, 3V to 26V operating range for the LP2902-N (absolute maximum 26V). |
| 5 | IN 2+ | input | Non-inverting input of amplifier 2; common-mode range includes ground. |
| 6 | IN 2- | input | Inverting input of amplifier 2; input voltage must not go more than -0.3V below GND. |
| 7 | OUT 2 | output | Output of amplifier 2. |
| 8 | OUT 3 | output | Output of amplifier 3. |
| 9 | IN 3- | input | Inverting input of amplifier 3; input voltage must not go more than -0.3V below GND. |
| 10 | IN 3+ | input | Non-inverting input of amplifier 3; common-mode range includes ground. |
| 11 | GND | power_in | Ground (negative supply, V-); inputs must not go more than -0.3V below it. |
| 12 | IN 4+ | input | Non-inverting input of amplifier 4; common-mode range includes ground. |
| 13 | IN 4- | input | Inverting input of amplifier 4; input voltage must not go more than -0.3V below GND. |
| 14 | OUT 4 | output | Output of amplifier 4. |
