# OPA1612AIDRGR

**Texas Instruments** · Audio Amplifiers · SON-8-EP(3x3)

OPA1612AIDRGR from Texas Instruments, in a SON-8-EP(3x3). 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 | Channel A operational amplifier output with ±30 mA drive capability and rail-to-rail swing within 600 mV of supply rails. |
| 2 | -IN A | input | Channel A inverting input for differential input configuration. |
| 3 | +IN A | input | Channel A non-inverting input; common-mode voltage range (V−)+2 V to (V+)−2 V. |
| 4 | V− | power_in | Negative power supply (minimum); total supply voltage differential (V+)−(V−) = 4.5 V to 36 V; bypass with 0.1 µF ceramic capacitor. |
| 5 | +IN B | input | Channel B non-inverting input; common-mode voltage range (V−)+2 V to (V+)−2 V. |
| 6 | -IN B | input | Channel B inverting input for differential input configuration. |
| 7 | OUT B | output | Channel B operational amplifier output with ±30 mA drive capability and rail-to-rail swing within 600 mV of supply rails. |
| 8 | V+ | power_in | Positive power supply (maximum); total supply voltage differential (V+)−(V−) = 4.5 V to 36 V; bypass with 0.1 µF ceramic capacitor. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
