16 Bit Digital to Analog Converter
PT8211
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 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 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.
