PAM8301AAF

Diodes Incorporated · Audio Amplifiers · SOT-23-6

PAM8301AAF from Diodes Incorporated, in a SOT-23-6. 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 Negative (inverted) class-D speaker output; drives the speaker directly with no low-pass filter, per the filterless architecture.
2 GND power_in Ground reference for the device; all voltages in the datasheet are referenced to ground.
3 IN input Audio input; an input coupling capacitor CI is required to bias the signal, with the internal input resistance RI at 10kΩ minimum forming the high-pass corner.
4 SD input Active-low shutdown; a logic low turns the amplifier off, and tying it to GND minimizes idle supply current (SHDN input high 1.2 V min, input low 0.4 V max).
5 VDD power_in Power supply input, rated 2.5 V to 5.5 V; needs local decoupling (about 1.0 µF low-ESR ceramic placed close to VDD plus 10 µF or larger).
6 OUT+ output Positive (non-inverted) class-D speaker output; used differentially with OUT- to drive the load.
