CS4101
The CS4101 is specifically designed
for use with air-core meter move-
ments. The IC provides all the func-
tions necessary for an analog
tachometer or speedometer. The
CS4101 takes a speed sensor input
and generates sine and cosine relat-
ed output signals to differentially
drive an air-core meter.
Many enhancements have been
added over industry standard
tachometer drivers such as the
CS-289 or LM1819. The output uti-
lizes differential drivers which elim-
inates the need for a zener reference
and offers more torque. The device
withstands 60V transients which
decreases the protection circuitry
required. The device is also more
precise than existing devices allow-
ing for fewer trims and for use in a
speedometer.
