PT8211L also enhanced the performanc e of timing responsibility in digital serial bus, in a company with the fast switching r-2r network that make 8x oversamp ling audio signal is also supported. PT8211L can be supported wide range of sample fr equency, 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. features ? cmos technology ? low supply voltage available (v dd =1.6v) ? support 3.3v bus input level or lower ? low power consumption ? two audio channel output in the same chip ? 16 bit dynamic range ? low total harmonic distortion ? no phase shift between both output channel ? available in 8 pins, sop or dip applications ? digital audio equipment ? cd rom/vcd ? multimedia sound card ? mpeg decoder card
