CS8190/D

CS8190

Precision Air−Core

Tach/Speedo Driver with

Return to Zero

The CS8190 is specifically designed for use with air−core meter

movements. The IC provides all the functions necessary for an analog

tachometer or speedometer. The CS8190 takes a speed sensor input

and generates sine and cosine related 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 utilizes

differential drivers which eliminates the need for a zener reference

and offers more torque. The device withstands 60 V transients which

decreases the protection circuitry required. The device is also more

precise than existing devices allowing for fewer trims and for use in a

speedometer.
