CS4101 is specially used for hollow core meter movement. This IC provides all functions necessary for an analog tachometer or odometer. The CS4101 takes the input of a speed sensor and produces a sine and cosine related output signal to differentially drive the meter hollow core. Many enhancements have been added over industry standards such as the tachometer driver CS-289 or LM1819. ...
