LM386D-1RG

HANSCHIP semiconductor · Audio Amplifiers · SOP-8

LM386D-1RG from HANSCHIP semiconductor, in a SOP-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 GAIN passive Gain control pin; with pins 1 and 8 open gain is 20 (26 dB), and a capacitor (optionally with series resistor) from pin 1 to pin 8 raises gain up to 200 (46 dB).
2 -INPUT input Inverting input, ground referenced and biased to ground with an internal 50 kΩ resistor.
3 +INPUT input Non-inverting input, ground referenced and biased to ground with an internal 50 kΩ resistor.
4 GND power_in Ground; all voltages are measured with respect to this pin.
5 VOUT output Amplifier output, automatically biased to one half the supply voltage.
6 VS power_in Positive supply; operating range 4V to 12V (LM386-1 types), absolute maximum 15V.
7 BYPASS passive Bypass pin for the internal bias node, decoupled with an external capacitor (10 µF used in PSRR test conditions).
8 GAIN passive Gain control pin; a capacitor from pin 1 to pin 8 bypasses the internal 1.35 kΩ resistor to increase gain up to 200.

CAD (KiCad official)

  • Symbol: LM386D-1RG
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm386d-1rg-etched.step / lm386d-1rg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm386d-1rg.step / lm386d-1rg.glb are the bare package body.
