NAU8814 is a cost effective and low power wideband MONO audio CODEC. It is designed for voice telephony related applications. Functions include 5-band Graphic Equalizer, Automatic Level Control (ALC) with noise gate, PGA, standard audio interface I²S, PCM with time slot assignment, and on-chip PLL. The device provides one differential microphone input and one single ended auxiliary input (multi purpose) .  There are few variable gain control stages in the audio path. It also includes MONO line output and integrated BTL speaker driver.

The analog inputs have PGA on the front end, allowing dynamic range optimization with a wide range of input sources. The microphone amplifiers have a programmable gain from -12dB to +35.25dB to handle both amplified microphones.  In addition to a digital high pass filter to remove DC offset voltages, the ADC also features voice band digital filtering. Voice band data is accepted by the audio interface (I²S) .  The DAC converter path includes filtering and mixing, programmable-gain amplifiers (PGA) , and soft muting. The digital interfaces, 2-Wire or SPI, have independent supply voltage to allow integration into multiple supply systems.  NAU8814 operates at supply voltages from 2.5V to 3.6V, although the digital core can operate at voltage as low as 1.71V to save power.
