LM4951ASD

Texas Instruments · Audio Amplifiers · WSON-10-EP(4x4)

LM4951ASD from Texas Instruments, in a WSON-10-EP(4x4). 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 Bypass output Half-supply reference voltage bypass output for power supply bypassing.
2 Shutdown input Active-low shutdown control signal; pulling low enters shutdown mode.
3 CCHG output Capacitor charge output to decrease turn-on time.
4 NC unconnected No connection to die; pin can be connected to any potential.
5 VIN power_in Single-ended signal input pin.
6 VO- output Inverting output of amplifier.
7 GND power_in Ground connection.
8 NC unconnected No connection to die; pin can be connected to any potential.
9 VDD power_in Power supply input.
10 VO+ output Non-inverting output of amplifier.
11 Exposed DAP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: LM4951ASD
  • Footprint: Package_SON:WSON-10-1EP_4x4mm_P0.8mm_EP2.6x3mm
  • 3D model: WSON-10-EP(4x4) (KiCad packages3D, STEP)
  • 3D model files: lm4951asd-etched.step / lm4951asd-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm4951asd.step / lm4951asd.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (24 pp, sha256 1a64bbe96db129c1, retrieved 2026-10-03, tier: lcsc)
