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 al so includes a digitally control lable
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 on-
chip mute, attenuation and phase reversal. A hardware
controllabl e inter fac e is al so availabl e.
