The LM4931 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 I2C/SPI compatible interface for control. The full range music path features an SNR of 86dB with an 18-bit 48kHz input. The headphone amplifier delivers at least 26mWRMS to a 32Ω single-ended stereo load with less than 1% distortion (THD+N) when AVDD = 3.3VDC. The mono speaker amplifier delivers up to 570mWRMS into an 8Ω load with less than 1% distortion when AVDD = 3.3VDC.
