DESCRIPTION

PT8211L 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 low supply voltage. PT8211L also enhanced the performance of timing responsibility in digital serial bus, in a company with the fast switching R-2R networkthat make 8X oversampling audio signal is also supported.

PT8211L 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. PT8211L is available in 8-pin SOP or DIP package.

PT8211L is designed for low voltage purpose, supply voltage can be down to 2V.
