DESCRIPTION
WM8733 is a high performance stereo DAC designed for use in
portable audio equipment, video CD players and similar
applications. It comprises selectable normal or I
S compatible
serial data interfaces for 16 to 24-bit inputs, high performance
digital filters, and sigma-delta output DACs, achieving an 102dB
signal-to-noise ratio.
The device is available in a 14-pin SOIC package that offers
selectable mute and de-emphasis functions using a minimum of
external components.
Low supply voltage operation and low current consumption are
valuable features, particularly for use in portable equipment.
Additional modes consist of a powerdown option and the
possibility of generating separate differential left and right
outputs for applications demanding higher performance.
