CSC2323

6-Ch Audio Selector CSC2323 DESCRIPTION CSC2323 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.
