## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of channel A. |
| 2 | -INA | input | Inverting input of channel A. |
| 3 | +INA | input | Noninverting input of channel A. |
| 4 | V- | power_in | Negative (lowest) power supply. |
| 5 | EnA | input | Enable pin for channel A: low disables the amplifier and high gives normal operation, and the pin must be driven. |
| 6 | EnB | input | Enable pin for channel B: low disables the amplifier and high gives normal operation, and the pin must be driven. |
| 7 | +INB | input | Noninverting input of channel B. |
| 8 | -INB | input | Inverting input of channel B. |
| 9 | OUTB | output | Output of channel B. |
| 10 | V+ | power_in | Positive (highest) power supply. |
