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

LM833MM 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 | OUT A | output | Output of amplifier A; output voltage swing ±12 V min into 2 kΩ with VS = ±15 V. |
| 2 | -IN A | input | Inverting input of amplifier A; input bias current 500 nA typ, 1000 nA max. |
| 3 | +IN A | input | Non-inverting input of amplifier A; input common-mode range ±12 V min, ±14 V typ at VS = ±15 V. |
| 4 | -VEE | power_in | Negative power supply; VCC-VEE total supply range up to 36 V absolute maximum. |
| 5 | -IN B | input | Inverting input of amplifier B; input bias current 500 nA typ, 1000 nA max. |
| 6 | +IN B | input | Non-inverting input of amplifier B; input common-mode range ±12 V min, ±14 V typ at VS = ±15 V. |
| 7 | OUT B | output | Output of amplifier B; output voltage swing ±12 V min into 2 kΩ with VS = ±15 V. |
| 8 | +VCC | power_in | Positive power supply; VCC-VEE total supply range up to 36 V absolute maximum; quiescent supply current 5 mA typ, 8 mA max for both amplifiers. |

## CAD (KiCad official)

- Symbol: `LM833MM`
- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`
- 3D model: VSSOP-8 (KiCad packages3D, STEP)
- 3D model files: `lm833mm-etched.step` / `lm833mm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm833mm.step` / `lm833mm.glb` are the bare package body.
