LM4851 Integrated Audio Amplifier System
General Description
The LM4851 is an audio power amplifier system capable of delivering 1.
1W (typ) of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N and 115mW (typ) per channel of continuous average power into stereo 32Ω 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, that allows flexibility in routing and mixing audio channels.
The LM4851 has 3 inputs: one pair for a ...
