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. s PACKAGE OUTLINE
