PT8211
16-Bit Digital to Analog Converter
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. Its 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.

APPLICATION CIRCUIT AND NOTE
To further suppress residual noise, we suggest placing an additional low pass filter after the analog output of PT8211.
Please refer to the circuit diagram below. This is a simple second-order analog post filter. If low noise output is very
important for your circuit design we suggest using a regulated power supply.
