4-Channel Electronic Volume with Input Selector
GENERAL DESCRIPTION PACKAGE OUTLINE
The NJW1195A is a 4-channel electronic volume with
4-in 2-out stereo audio selector. It perf o rms low noise and
low distortion character istics with resistance ladder circuit.
The NJW1195A is a ls o available for 2-channel differential
transmission electronic volume with 2-in 1-out stereo audio
selector by a differential transmission select function.
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.
At the volume attenuated, the NJW1195A improves low
distortion compared with NJW1195. Furthermore, the
NJW1195A supports bot h single power supply opera tion
and dual power supply operation.

In this case, Volume Control 1 becomes effective and does not accept Volume Control 2 about Contro l Data.
Also, each selector becomes independent control.

because of keeping high channel separation. (On e OpAmp is for A_REF terminal use, th e other on e is for
