NAU85L40YGB

The NAU85L40YGB is a low power, high quality, 4 channel ADC for microphone array application. The NAU85L40YGB integrates programmable gain preamplifiers for quad differential microphones, significantly reducing external component requirements. Audio data can be directed to two I²S data outlines or onto a single time division multiplexed (TDM) PCM data output.
