LM4876MX

Texas Instruments · Audio Amplifiers · SOIC-8

LM4876MX 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 SHUTDOWN input Active-low micro-power shutdown input; shutdown is activated below 400mV (VIL 0.4V max, VIH 1.2V min) and should be tied to ground for lowest shutdown current.
2 BYPASS passive Half-supply bypass node; a 1µF capacitor to ground improves PSRR and sets turn-on settling for click and pop performance.
3 +IN input Non-inverting input of Amp1.
4 -IN input Inverting input of Amp1, connected through Ri and Ci to the signal with Rf feedback setting gain AVD = 2*(Rf/Ri).
5 Vo1 output Amp1 output, one side of the bridge-tied load.
6 VDD power_in Positive supply, 2.0V to 5.5V operating range (6.0V absolute max), bypassed locally with a capacitor to ground.
7 GND power_in Ground.
8 Vo2 output Amp2 output (gain of -1 from Amp1), the other side of the bridge-tied load.

CAD (KiCad official)

  • Symbol: LM4876MX
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm4876mx-etched.step / lm4876mx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm4876mx.step / lm4876mx.glb are the bare package body.
