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

The LM49370 includes a high quality stereo DAC, a mono ADC, a stereo headphone amplifier, which supports output cap-less (OCL) or AC-coupled (SE) modes of operation, a mono earpiece amplifier, and an

LM49370 Features

* 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 lea
