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.
 
Integrated power-limit technology suppresses the output signal clip automatically due to the over level input signal. This technology also offers low THD+N and protects speaker.
 
Integrated Undervoltage Protection (UVP) technology, external undervoltage detection can be used to shut down the PAM8009 before an input device can generate a pop.
 
PAM8009 is available in SO-24 and U-QFN4040-20.
