DESCRIPTION CONTINUED

The LM49350 features dual bi-directional I2S or PCM audio interfaces for full range audio and an I2C compatible

interface for control. The stereo DAC path features an SNR of 96dB with 24-bit 48 kHz input. The headphone

amplifier delivers 69mWRMS (typ) to a 32Ω single-ended stereo load with less than 1% distortion (THD+N) when

A_VDD = 3.3V. The earpiece speaker amplifier delivers 58mWRMS (typ) to a 32Ω bridged-tied load with less than

1% distortion (THD+N) when A_VDD = 3.3V. The loudspeaker amplifier delivers up to 495mW into an 8Ω load

with less than 1% distortion when LS_VDD = 3.3V and up to 1.2W when LS_VDD = 5.0V.

The LM49350 employs advanced techniques to reduce power consumption, to reduce controller overhead, to

speed development time, and to eliminate click and pop. Boomer audio power amplifiers were designed

specifically to provide high quality output power with a minimal amount of external components. It is therefore

ideally suited for mobile phone and other low voltage applications where minimal power consumption, PCB area

and cost are primary requirements.
