TECHNICAL DATA
Precision Air-Core Tach/Speedo Driver
with Return to Zero
Functional Description
The IL8190N is specifically designed for use with air–core
meter movements. The IC provides all the functions
necessary for an analog tachometer or speedometer. The
IL8190N takes a speed sensor input and generates sine
and cosine related output signals to differentially drive an
air–core meter.
