DESCRIPTION

The WM8720 is a high performance stereo DAC designed

for audio applications such as CD, DVD, home theatre

systems, set top boxes and digital TV. The WM8720

supports data input word lengths from 16 to 24-bits and

sampling rates up to 96kHz. The WM8720 consists of a

serial interface port, digital interpolation filter, multi-bit

sigma delta modulator and stereo DAC in a small 20-pin

SSOP package. The WM8720 also includes a digitally

controllable mute and attenuator function on each channel.

The WM8720 supports a variety of 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

controllable interface is also available.

The programmable data input port supports a variety of

glueless interfaces to popular DSPs, audio decoders and

S/PDIF and AES/EBU receivers.
