16 Bit Digital to Analog Converter
PT8211L
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 network that 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.

APPLICATION CIRCUIT AND NOTE
For further suppress residual noise, we suggestion place an additional low pass filter after the analog
output of PT8211L. Please refer to circuit shown on below, this is a simple second-order analog post
filter. If low noise output is very important for your circuit design we suggestion uses regulated power
supply.
