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 an R-2R resister ladder network, an internal circuit is well matched and a 16 bit dynamic range is achieved even in whole supply voltage range.
PT8211 also enhanced the performance of timing responsibility in a digital serial bus, in a company with the fast switching R-2R network that makes 8X oversampling audio signal is also supported. PT8211 can be supported by a wide range of sample frequency, it is compatible with TDA1311 by functionally. Its 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 SO or DIP package.
