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. A configurable sound engine provides enhanced record and playback processing to improve overall audio quality. 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.
