8-CHANNEL ELECTRONIC VOLUME WITH INPUT SELECTOR
s GENERAL DESCRIPTION
NJW1157 is an eight channel electronic volume IC.
It includes Input selector, tone control, volume, mute,
input selector gain control, volume output gain control
and 5 REC outputs. It’s suitable for multi-channel
audio equipments such as AV receivers and DVD
receivers. These functions are controlled by
three-wired serial data.
