NJRC NJW1194

NJW1194
2-CHANNEL ELECTRONIC VOLUME
WITH INPUT SELECTOR AND TONE CONTROL
■ GENERAL DESCRIPTION
■PACKAGE OUTLINE
The NJW1194 is a 2-channel electronic volume with4-in 1-out
stereo audio selector and Tone Control. The NJW1194 performs
low noise and low distortion characteristics with resistance ladder
circuit.
All of functions are controlled via three-wired serial bus.
Selectable 4-Chip address is available for using four chips on
same serial bus line.
It’s suitable for two-channel stereo system and or multi-channel
audio system.
