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.
