CS8190_06 Datasheet, PDF (1/11 Pages) ON Semiconductor – Precision Air−Core Tach/Speedo Driver with Return to Zero

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.
