NAU8810YG Differential/Mono Audio codec IC

The NAU8810 a cost effective low power wideband Monophonic audio CODEC. It is suitable for a wide range of audio applications, including voice telephony. The NAU8810 a Mono Audio CODEC with very robust ADC and DAC capabilities. The device provides one differential microphone input pair (MIC- & MIC+ pins) supported by a two-stage amplification path for amplification by as much as 55.25dB. The NAU88U10 has a 2-Wire read/write serial control interface for device control. Audio data is supported in many commonly used industry formats as either I2S or PCM formatted data.
