LM4852 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, using 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 I2C compatible 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.
