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.
