6 Channel Audio Selector SJ2323
DESCRIPTION
SJ2323 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.
