PAM8019
3W STEREO CLASS-D AUDIO AMPLIFIER AND CLASS AB HEADPHONE DRIVER
WITH DC VOLUME CONTROL, NON-CLIP POWER LIMIT AND UVP
Description
The PAM8019 is a Stereo 3W Class D audio power amplifier for
driving bridged-tied speakers and includes a Stereo Class AB amplifier
for driving headphones. The advanced 64 step DC volume control
minimizes external components allowing simple and accurate volume
control over the gain range of +20dB (Volume=0V) to -60dB
(Volume=5V).
Integrated non-clip power limit technology suppresses output
automatically with programmable power limit, improving the sound
quality and helping to protect the speakers. Programmable under
voltage protection (UVP) can be used to shut down the PAM8019 at a
pre-determined voltage level helping to eliminate speaker pop by
shutting down before the power supply collapses.
The PAM8019 is available in the power efficient and space saving
U-QFN4040-20.
