The LM4930 is an integrated audio subsystem that supports voice and digital audio functions.

an I2S serial interface for full range audio, a 16-bit PCM bi-directional serial interface for the voice band codec and an two-wire interface for control. The full range music path features an SNR of 86dB with a 16-bit 48kHz input. The stereo DAC can also be used while the voice codec is in use. The headphone amplifier delivers 25mWRMS to a 32Ω single-ended stereo load with less than 0.5% distortion (THD+N) when AVDD = 3V. The mono speaker amplifier delivers up to 300mW into an 8Ω load with less.
