... The CS8190 is specifically designed for use with air-core meter move- ments. The IC provides all the func- tions necessary for an analog tachometer or speedometer. The CS8190 takes a speed sensor input and generates sine and cosine relat- ed output signals to differentially drive an air-core meter. Many enhancements have been ...
