LM4880MX

Texas Instruments · Audio Amplifiers · SOIC-8

LM4880MX 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 Channel A amplifier output, AC-coupled to the load through output coupling capacitor Co.
2 IN A input Channel A inverting input, with gain set by Ri and RF and coupled through input capacitor Ci.
3 BYPASS passive Half-supply bypass pin that takes capacitor CB (1.0 µF or larger recommended) for PSRR and turn-on click and pop performance.
4 GND power_in Ground pin, the reference for all voltages.
5 SHUTDOWN input Shutdown control: a logic high (trigger point typically half supply) turns the amplifier off, and the pin must be tied to a definite voltage, not left floating.
6 IN B input Channel B inverting input, with gain set by Ri and RF and coupled through input capacitor Ci.
7 OUT B output Channel B amplifier output, AC-coupled to the load through output coupling capacitor Co.
8 VDD power_in Positive supply, 2.7V to 5.5V operating (6.0V absolute maximum), with a supply bypass capacitor placed close to the pin.

CAD (KiCad official)

  • Symbol: LM4880MX
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm4880mx-etched.step / lm4880mx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm4880mx.step / lm4880mx.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
