ADAU1979 Description
The ADAU1979 incorporates four high performance, analog-to-digital converters (ADCs) with 4.5 V rms capable ac-coupled inputs. The ADCs use a multibit sigma-delta (ΣΔ) architecture with continuous time front end for low EMI. An I2C/serial peripheral interface (SPI) control port is included that allows a microcontroller to adjust volume and many other parameters.
