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 onchip 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.
