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. ■ FEATURES ● Operating Voltage ● 3-Wired Serial Control ● Low output noise ● Low THD ● Input Selector(X4) ● Volume ● Tone Control ● Channel Separation ● Zero Cross Detection ● Bi-CMOS Technology ● Package Outline NJW1194V ±4.5 to ±7.5V Chip Address Select Function -117dBVtyp. 0.0015%typ.
