NJW1153
6-CHANNEL ELECTRONIC VOLUME WITH INPUT SELECTOR
I
GENERAL DESCRIPTION
NJW1153
is a 6-channel electronic volume IC. It
includes Input selector, tone control, volume, mute, input
selector gain control, volume output gain control and 3
REC outputs. Each mode and conditions are set by the
3-wired serial control data.
