LM4852
Integrated Audio Amplifier System
General DescriptionThe LM4852isan audio power amplifier system capableof
delivering 1.1W (typ)of continuous average power intoa
mono 8Ω bridged-tied load (BTL) with 1% THD+N and
60mW (typ) per channelof continuous average power into
stereo 32Ω single-ended (SE) loads with 0.5% THD+N, us-
inga5V power supply.
The LM4852 featuresa32 step digital volume control and
eight distinct output modes. The digital volume control and
output modesare programmed througha two-wireI2C com-
patible control interface, that allows flexibilityin routing and
mixing audio channels. The LM4852 has3 channels: one
pairfora two-channel stereo signal and the thirdfora
single-channel mono input.
The LM4852is designedfor cellular phone, PDA, and other
portable handheld applications.It delivers high quality output
power froma surface-mount package and requires only
seven external components.
The industry leading micro SMD package only utilizes 2mm 2.3mmof PCB space, makingthe LM4852the most space
efficient audio sub system available today.
