NJM2186 PRELIMINARY DOLBY S-TYPE NOISE REDUCTION PROCESSOR ■PACKAGE OUTLINE ■GENERAL DISCRIPTION The NJM2186 is a stereo Dolby S-type noise reduction processor. It applies to stereo system on 1 chip because it includes dual channel circuit. The NJM2186 contains all of necessary block for decoding operation, and it also performs encoding operation by connecting two external operational amplifiers. + The feature of minimum operating voltage from 7.5V(V /V = ±3.75V)is most suitable for car audio applications.
