16 Bits Digital-to-Analog Converter IC
PT8215
Description
PT8215 is a 16 bits Digital-to-Analog Converter IC utilizing CMOS Technology.
PT8215 converts the 16 bits serial data into an analog output current. 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 Current. Thus, 16 bits
dynamic range is achieved. The current of each output channels of PT8215 is
driven by an operational amplifier allowing easy analog output
PT8215 can be pin-to-pin compatible with TDA1545 by modifying the bias
circuit. It can be used with the Japanese input formats: time multiplexed, two鈥檚
complement, MSB first TTL level serial input data. It has been tested on sound
card with the popular 44.1 KHz sampling rate and can be used at a higher
sampling rate. PT8215 is housed in an 8-pin SO or DIP Package.
