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

LM833DGKR from Texas Instruments, in a VSSOP-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 | OUT1 | output | Output of the first operational amplifier with voltage swing from approximately -14.6 V to 14.1 V. |
| 2 | IN1- | input | Inverting input of the first operational amplifier; input voltage must be between VCC- and VCC+. |
| 3 | IN1+ | input | Noninverting input of the first operational amplifier; input voltage must be between VCC- and VCC+. |
| 4 | VCC- | power_in | Negative supply voltage, rated from -18 V to -5 V. |
| 5 | IN2+ | input | Noninverting input of the second operational amplifier; input voltage must be between VCC- and VCC+. |
| 6 | IN2- | input | Inverting input of the second operational amplifier; input voltage must be between VCC- and VCC+. |
| 7 | OUT2 | output | Output of the second operational amplifier with voltage swing from approximately -14.6 V to 14.1 V. |
| 8 | VCC+ | power_in | Positive supply voltage, rated from +5 V to +18 V. |

## CAD (KiCad official)

- Symbol: `LM833DGKR`
- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`
- 3D model: VSSOP-8 (KiCad packages3D, STEP)
- 3D model files: `lm833dgkr-etched.step` / `lm833dgkr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm833dgkr.step` / `lm833dgkr.glb` are the bare package body.
