| NJW1194 2-CHANNEL ELECTRONIC VOLUME WITH INPUT SELECTOR AND TONE CONTROL s GENERAL DESCRIPTION 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. sPACKAGE OUTLINE NJW1194V s FEATURES q Operating Voltage q 3-Wired Serial Control q Low output noise q Low THD q Input Selector(X4) q Volume q Tone Control q Channel Separation q Zero Cross Detection q Bi-CMOS Technology q Package Outline 4.5 to 7.5V Chip Address Select Function -117dBVtyp. 0.0015%typ.
