NJW1159
2-CHANNEL ELECTRONIC VOLUME
s GENERAL DESCRIPTION
NJW1159 is a two channel electronic volume IC. It
is included output buffer amplifier and also resistor
output terminal for using external amplifier to
customize for your application. These functions are
controlled by three-wired serial data. And the chip
selector is available for using four chips on same
serial bus line. It’s available for two-channel stereo
and or multi-channel audio volume.
