PAM8009
3W STEREO CLASS-D Audio Amplifier and Class AB
Headphone Driver (DC VOLUME, UVP and AGC Function)
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. 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.
