General Description

HT82V731 is a 16-bit digital-to-analog converter IC uti-

lizing CMOS technology specially designed for stereo

audio application.

HT82V731 converts the 16 bits serial data into an ana-

log output voltage. The digital data is internally con-

verted to floating point expression whose format

consists of 10 bits mantissa and 7step exponent.

Using an R-string voltage divider, this floating point ex-

pression data is then converted to analog voltage.

It is compatible with TDA1311. It is available in 8-pin

SOP package.
