GENERAL DESCRIPTION
The ADAU1781 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
ADAU1781 ideal for battery-powered audio applications.
A programmable SigmaDSP core 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 ADAU1781 includes a stereo
line output and speaker driver, which makes the device capable of
supporting dynamic speakers.
The serial control bus supports the I2C or SPI protocols, and
the serial audio bus is programmable for I2S, left-justified, right-
justified, or TDM mode. A programmable PLL supports flexible
clock generation for all standard rates and available master clocks
from 11 MHz to 20 MHz.
