NAU8814 1. GENERAL DESCRIPTION Mono Audio Codec with Speaker Driver and Equalizer emPowerAudio™ 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.
