LM4852 May 2004 Integrated LM4852Integrated Audio Amplifier SystemGeneral Description Key Specifications The LM4852 is an audio power amplifier system capable of n THD+N at 1kHz, 1.1W into 8 BTL 1.0% (typ) delivering 1.1W (typ) of continuous average power into a Audio n THD+N at 1kHz, 60mW into 32 SE 0.5% (typ) mono 8 bridged-tied load (BTL) with 1% THD+N and n Single Supply Operation 2.6 to 5.0V 60mW (typ) per channel of continuous average power intostereo 32 single-ended (SE) loads with 0.5% THD+N, us- Features ing a 5V power supply. Amplifier n 1.1W (typ) output power with 8 mono BTL load The LM4852 features a 32 step digital volume control and n 60mW (typ) output power with stereo 32 SE loads eight distinct output modes. The digital volume control andoutput modes are programmed through a two-wire I2C com- n I2C programmable 32 step digital volume control patible control interface, that allows flexibility in routing and (-40.5dB to +6dB) mixing audio channels. The LM4852 has 3 channels: one n Eight distinct output modes pair for a two-channel stereo signal and the third for a n micro-SMD and LLP surface mount packaging single-channel mono input. n "Click and Pop" suppression circuitry System The LM4852 is designed for cellular phone, PDA, and other n Thermal shutdown protection portable handheld applications. It delivers high quality output n Low shutdown current (0.1uA, typ) power from a surface-mount package and requires onlyseven external components. Applications The industry leading micro SMD package only utilizes 2mm n Moblie Phones x 2.3mm of PCB space, making the LM4852 the most space n PDAs efficient audio sub system available today.
