4-Channel Electronic Volume with Input Selector

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJW1195 is a 4-channel electronic volume with 4-in

2-out stereo audio selector. It performs low noise and low

distortion characteristics with resistance ladder circuit.

The NJW1195 is also 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.
