NJU72343
8-CHANNEL ELECTRONIC VOLUME
GENERAL DESCRIPTION
The NJU72343 is a 8-channel electronic volume that controlled
independently. It has a 2-input selector for 4 of 8-channels.
Functions are controlled via two-wired serial bus.
The NJU72343 is well-suited for multi-channel audio systems
such as AV amplifiers, DVD receivers and others.
