NAU8401 datasheet

Description :

The NAU8401 is a low power, high quality audio output system for portable applications. In addition to precision 24-bit stereo DACs, this device integrates a broad range of additional functions to simplify implementation of complete audio systems. 

The NAU8401 includes drivers for speaker, headphone, and stereo line outputs, and integrates mixing of the DAC outputs with analog input signals. Advanced on-chip digital signal processing includes a 5-band equalizer, a 3-D audio enhancer, and a digital limiter/dynamic range compressor function for the playback path. The digital interface can operate as either a master or a slave.  Additionally, an internal fractional-N  PLL is available to generate accurate audio sample rate clocks for the DAC derived from any available system clock from 8MHz through 33MHz.
