NAU8820 Low Power 24-bit Stereo Audio Codec with High Current Outputs emPowerAudio™ Description The NAU8820 is a low power, high quality CODEC for portable applications. In addition to precision 24-bit stereo ADCs and DACs, this device integrates a broad range of additional functions to simplify implementation of complete audio system solutions. The NAU8820 includes drivers for headphones, and differential or stereo line outputs, and integrates preamps for stereo differential microphones, significantly reducing external components. Advanced on-chip digital signal processing includes a 5-band equalizer, a 3-D audio enhancer, a mixed-signal automatic level control for the microphone or line input through the ADC, and a digital limiter function for the playback path.
