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 NAU-8401 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.

Features

1. DAC: 94dB SNR and -84dB THD (“A” weighted)
2. Integrated BTL speaker driver: 1W into 8Ω
3. Integrated head-phone driver: 40mW into 16Ω
4. Integrated line inputs and line outputs
5. On-chip high resolution fractional-N PLL

Applications:

1. Personal Navigation Devices
2. Personal Media Players
3. Personal Navigation Devices
