**Texas Instruments** · Audio Amplifiers · SOIC-8

OPA1612AID from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of channel A with rail-to-rail swing to within 600 mV at 2-kΩ load. |
| 2 | -IN A | input | Inverting input of channel A; input voltage range (V-) - 0.5 V to (V+) + 0.5 V. |
| 3 | +IN A | input | Noninverting input of channel A; input voltage range (V-) - 0.5 V to (V+) + 0.5 V. |
| 4 | V- | power_in | Negative (lowest) power supply; supply voltage range (V+ - V-) 4.5 V to 36 V. |
| 5 | +IN B | input | Noninverting input of channel B; input voltage range (V-) - 0.5 V to (V+) + 0.5 V. |
| 6 | -IN B | input | Inverting input of channel B; input voltage range (V-) - 0.5 V to (V+) + 0.5 V. |
| 7 | OUT B | output | Output of channel B with rail-to-rail swing to within 600 mV at 2-kΩ load. |
| 8 | V+ | power_in | Positive (highest) power supply; supply voltage range (V+ - V-) 4.5 V to 36 V. |
