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.
