General Description

HT82V731 is a 16-bit digital-to-analog converter IC uti
lizing CMOS technology specially designed for stereo
audio application. It converts the 16 bits serial data into
an analog output voltage by high precision D/A con
verter.

With its excellent frequency response characteristics,
the HT82V731 provides users a low cost means of im-
