General Description

The PAM8009 is a 3W, Class D audio-power amplifier for driving bridged-tied stereo speakers.

Advanced DC volume control minimizes external components and allows BTL (Speaker) volume control and SE (Headphone) volume control, the gain range is from +20dB (Volume=5V) to -60dB (Volume=0V) with 64 steps precise control.

Pin Assignments Integrated power-limit technology suppresses the output signal clip automatically due to the over level input signal.
