LM4852
Integrated Audio Amplifier System
General Description
The LM4852 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
60mW (typ) per channel of continuous average power into
stereo 32
single-ended (SE) loads with 0.5% THD+N, us-
ing a 5V power supply.
The LM4852 features a 32 step digital volume control and
eight distinct output modes. The digital volume control and
output modes are programmed through a two-wire I
2C com-
patible control interface, that allows flexibility in routing and
mixing audio channels. The LM4852 has 3 channels: one
pair for a two-channel stereo signal and the third for a
single-channel mono input.
The LM4852 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
seven external components.
The industry leading micro SMD package only utilizes 2mm
x 2.3mm of PCB space, making the LM4852 the most space
efficient audio sub system available today.
