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.
