LM4851
Integrated Audio Amplifier System
General Description
The LM4851 is an audio power amplifier system capable of
delivering 1W (typ) of continuous average power into a mono
8
bridged-tied load (BTL) with 1% THD+N and 100mW
(typ) per channel of continuous average power into stereo
32
BTL loads with 0.5% THD+N, using a 5V power supply.
The LM4851 features a 32 step digital volume control and
eight distinct output modes. The digital volume control and
output modes are programmed through a three-wire SPI
serial control interface.
