ADAU1381

Low Noise Stereo Codec with Enhanced Recording and Playback Processing ADAU1381 FEATURES GENERAL DESCRIPTION 24-bit stereo audio ADC and DAC 400 mW speaker amplifier (into 8 Ω load) Built-in sound engine for audio processing Wind noise detection and autofiltering Enhanced stereo capture (ESC) The ADAU1381 is a low power, 24-bit stereo audio codec. The low noise DAC and ADC support sample rates from 8 kHz to 96 kHz. Low current draw and power saving modes make the ADAU1381 ideal for battery-powered audio applications. Dual-band automatic level control (ALC) A configurable sound engine provides enhanced record and 6-band equalizer, including notch filter playback processing to improve overall audio quality. Sampling rates from 8 kHz to 96 kHz Stereo pseudo differential microphone input Optional stereo digital microphone input pulse-density modulation (PDM) Stereo line output PLL supporting a range of input clock rates Analog and digital I/O 1.8 V to 3.3 V Software control via SigmaStudio graphical user interface The record path includes two digital stereo microphone inputs and an analog stereo input path. The analog inputs can be configured for either a pseudo differential or a single-ended stereo source. A dedicated analog beep input signal can be mixed into any output path. The ADAU1381 includes a stereo line output and speaker driver, which makes the device capable of supporting dynamic speakers. Software-controllable, clickless mute Software register and hardware...
