LM49350 - High Performance Audio Codec Sub-System

Description

The LM49350 is a high performance audio subsystem that supports both analog and digital audio functions.

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 4.
