DESCRIPTION
●PT8211 is a dual channel, 16 bit Digital-to-Analog Converter IC utilizing CMOS technology specially designed for the digital audio applications. The internal conversion architecture is based on a R-2R resister ladder network, internal circuit is wellmatched and a 16 bit dynamic range is achieved even in whole supply voltage range. PT8211 also enhanced the performance of timing responsibility in digital serial bus, in a company with the fast switching R-2R network that make 8X oversampling audio signal is also supported.
●PT8211 can be supported wide range of sample frequency, it is compatible with TDA1311 by
●functionally. It’s digital input timing format is Least Significant Bit Justified (LSBJ), or so called
●Japanese input format. Digital code format is two’s complement and MSB first. PT8211 is available in 8-pin SOP or DIP.
