5V or 3.3V supply operation

Sampling frequency: 8kHz to 96kHz

Input data word: 16 to 24-bit

Hardware or SPI compatible serial port control modes:

Hardware mode: system clock, reset, mute,

de-emphasis

Serial control mode: mute, de-emphasis, digital

attenuation (256 steps), zero mute, phase reversal,

power down

The WM8720 supports a variety of connection schemes for
