PAM8019KGR

PAM8019 3W STEREO CLASS-D AUDIO AMPLIFIER AND CLASS AB HEADPHONE DRIVER WITH DC VOLUME CONTROL, NON-CLIP POWER LIMIT AND UVP Pin Assignments 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). VDD LOUTP GND ROUTP 20 VDD Top View 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.
