The LM49370 is an integrated audio subsystem that supports both analog and digital audio functions.

a bi-directional I2S interface and a bidirectional PCM interface for full range audio on either interface. The LM49370 utilizes an I2C or SPI compatible interface for control. The stereo DAC path features an SNR of 85 dB with an 18-bit 48 kHz input. In SE mode the headphone amplifier delivers at least 33 mWRMS to a 32Ω single-ended stereo load with less than 1% distortion (THD+N) when A_VDD = 3.3V. The mono earpiece amplifier delivers at least 115mWRMS to a 32Ω bridged-tied load with less than 1.
