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’s

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.
