General Description HT82V731 is a 16-bit digital-to-analog converter IC utilizing CMOS technology specially designed for stereo audio application. HT82V731 converts the 16 bits serial data into an analog output voltage. The digital data is internally converted to floating point expression whose format consists of 10 bits mantissa and 7step exponent. Using an R-string voltage divider, this floating point expression data is then converted to analog voltage. It is compatible with TDA1311. It is available in 8-pin SOP package.
