NAU85L20YGB is a low power, high quality, 2-channel ADC for microphone array application. This part integrates programmable gain preamplifiers for stereo differential microphones, significantly reducing external component requirements.

A fractional FLL is available to accurately generate audio sample rate using system clock source from 8MHz through 33MHz. Audio data can be directed to two I²S data out lines or onto a single time division multiplexed (TDM) PCM data output.

NAU85L20YGB operates with analog supply voltages from 1.6V to 2V, while the digital core can operate down to 1.2V to conserve power. NAU85L20YGB provides register control to enable flexible power saving modes by powering down sub-sections of the IC.
