DESCRIPTION
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-Channelaudio 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.
