PT2323 is a 6-Channel Audio Selector utilizing CMOS Technology specially designed for Home
Theater System. It provides a built-in 2-Channel to 6-Channel Translator, which can directly mix
traditional stereo channel to simulate a 6-Channel audio output. Single power supply (9V), I2C Bus
Interface as well as very low Total Harmonic Distortion (THD < 0.005 ) and other features are
incorporated into a single chip thereby providing very high performance. Pin assignments and
application circuit are optimized for easy PCB layout and cost saving advantages.
