NJW1197C
8-CHANNEL ELECTRONIC VOLUME WITH INPUT SELECTOR
GENERAL DESCRIPTION PACKAGE OUTLINE
NJW1197C is an 8-channel electronic volume IC. It
includes Input selector, tone control, volume, mute, input
selector gain control, volume output gain control and 5
REC outputs. Each mode and conditions are set by the
3-wired serial control data.
NJW1197C improves low Residual Output Noise
Voltage compared with NJW1197.
