Overview
w WM8716 High Performance 24-bit, 192kHz Stereo DAC DESCRIPTION The WM8716 is a high performance stereo DAC designed for audio applications such as CD, DVD, home theatre systems, set top boxes and digital TV.
The WM8716 supports data input word lengths from 16 to 24-bits and sampling rates up to 192kHz.
The WM8716 consists of a serial interface port, digital interpolation filter, multi-bit sigma delta modulator and stereo DAC in a small 28-lead SSOP package.
The WM8716 also includes a digitally controllable mute and attenuator function on each channel.
The internal digital filter has two selectable roll-off characteristics.
A sharp or slow roll-off can be selected dependent on application requirements.
Additionally, the internal digital filter can be by-passed and the WM8716 used with an external digital filter.
The WM8716 supports two connection schemes for audio DAC control.
The SPI-compatible serial control port provides access to a wide range of features including onchip mute, attenuation and phase reversal.
A hardware controllable interface is also available.
