供应 PT8211-S 音频解码芯片

PT8211-S is a 16 bits Digital-to-Analog Converter IC utilizing CMOS Technology specially designed forstereo audio applications. PT8211-S converts the 16 bits serial data into an analog output voltage. Thedigital data is internally converted to floating point expression whose format consists of 10 bits mantissaand 7-step exponent. Using an R-string voltage divider, this floating point expression data is thenconverted to Analog Voltage. Thus, 16 bits dynamic range is achieved. The voltage of each outputchannel of PT8211-S is driven by an operational amplifier allowing easy analog output.

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