PAM8304ASR

Diodes Incorporated · Audio Amplifiers · MSOP-8

PAM8304ASR from Diodes Incorporated, in a MSOP-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+ output Positive BTL (bridge-tied load) output of the Class-D amplifier, driving the speaker together with OUT-.
2 PVDD power_in Power supply pin for the output stage (power supply per the datasheet; no separate voltage limit is stated for this pin beyond the 2.8V to 6.0V VDD range).
3 VDD power_in Analog power supply, specified at 2.8V to 6.0V (VDD absolute maximum 6.5V).
4 IN- input Negative differential audio input.
5 IN+ input Positive differential audio input.
6 /SD input Shutdown terminal, active low: a logic low or ground applied here puts the amplifier into standby with minimized supply current (input high level 1.4V min at VDD = 5V, low level 0.4V max).
7 GND power_in Ground reference for the device.
8 OUT- output Negative BTL (bridge-tied load) output of the Class-D amplifier, driving the speaker together with OUT+.

CAD (KiCad official)

  • Symbol: PAM8304ASR
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: pam8304asr-etched.step / pam8304asr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pam8304asr.step / pam8304asr.glb are the bare package body.
