An SPI/I2C port is included, allowing a microcontroller to adjust volume and many other parameters. The ADAU1966 operates from 2.5 V digital, 5 V analog and 3.3 V or 5 V input/output supplies. A linear regulator is included to generate the digital supply voltage from the analog supply voltage. The ADAU1966 is available in an 80...
