Integrated Audio Amplifier System

The LM4851 is an Audio Power Amplifier system capable of delivering 1.1W (typ) of continuous average power into a mono 8 bridged-tied load (BTL) with 1% THD+N and 115mW (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 that allows flexibility in routing and mixing Audio channels. The LM4851 has 3 inputs: one pair for a two-channel stereo signal and the third for a single-channel mono input.
The LM4851 is designed for cellular phone, PDA, and other portable handheld applications. It delivers high quality output power from a surface-mount package and requires only five external components.
The industry leading micro SMD package utilizes only 2mm x 2.3mm of PCB space, making the LM4851 the most space efficient Audio sub system available today.
