PT8211

PT8211 is a 16 bits Digital-to-Analog Converter IC utilizing CMOS Technology specially designed for stereo audio applications. PT 8211 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 7-step exponent. Using an R-string voltage divider, this floating point expression data is then converted to Analog Voltage. Thus, 16 bits dynamic range is achieved. The voltage of each output channel of PT 8211 is driven by an operational amplifier allowing easy analog output.

PT8211 has been tested on sound cards with the popular 44.1 KHz sampling rate and can be used at higher sampling rates. It is compatible with TDA1311 and can be used with the popular Japanese input formats time multiplexed, two's complement, MSB first TTL level serial input data. PT8211 is available in 8-pin SO or DIP Package.
