GENERAL DESCRIPTION

The NAU88C10is a cost effective low power wideband Monophonicaudio CODEC.  It issuitable for a wide range of  audio  applications,  includingvoice  telephony.   Supported  functions  includea5-band  Graphic  Equalizer, Automatic  Level  Control  (ALC)  with  noise  gate,  PGA,  standard I2S  or  PCM audio  interface, optional PCM  time slot assignment, anda full fractional-Non-chip PLL.  Thisdevice includesone differential microphone input, and multiple variable gain control stages in the audio paths.  Both a Mono headset/line-leveloutput andahigh power differential BTLspeaker driver output are provided.


The analog input path includesaPGA enablingdynamic range optimization ofa wide range of input sourceswith programmable gain from -12dB to +35.25dB.  In addition to a digital high pass filter to remove DC offset voltages, the  ADC  also  features programmable voice  band  digital  filtering.   Audio data iscommunicated  viatheaudio interfacethat  supports  multiple  I2S  and  PCM  data  formats.    The  DAC  converter  path  includes  filtering,mixing, programmable-gain  amplifiers,  and  soft  muting.    The 2-Wire digital control  interfacehasan independent  supply voltage  to enable  easyintegration  into  multiple  supplyvoltagesystems.   The NAU88C10operates  at  supply voltages from 2.5V to 3.6V, andthe digital core can operate at a voltage as low as 1.71V to conservepower.
