The IC provides all the func- tions necessary for an analog tachometer or speedometer. The CS4121 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 added over industry standard tachometer drivers such as the CS289 or LM1819. The output uti- lizes differential drivers which elim- inates the need for a zener reference and offers more torque. The device withstands 60V transients which decreases the protection circuitry required. The device is also more precise than existing devices allow- ing for fewer trims and for use in a speedometer. The CS4121 is compatible with the CS8190, and provides higher accu- racy at a lower supply voltage (8.0V min. as opposed to 8.5V). It is func- tionally operational to 6.5V.
