NAU8822L

NAU8822L 24-bit Stereo Audio Codec with Speaker Driver Description The NAU8822L is a low power, high quality CODEC for portable and general purpose audio 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 NAU8822L includes drivers for speaker, headphone, and differential or stereo line outputs, and integrates preamps for stereo differential microphones, significantly reducing external component requirements. Also, a fractional PLL is available to accurately generate any audio sample rate for the CODEC using any commonly available system clock from 8MHz through 33MHz. 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/dynamic-rangecompressor (DRC) function for the playback path.
