Description
The CS8191 is specifically designed
for use with 4 quadrant air-core
meter movements. The IC includes
an input comparator for sensing
input frequency such as vehicle
speed or engine RPM, a charge
pump for frequency to voltage con-
version, a bandgap reference for
stable operation and a function
generator with sine and cosine
tional operation down to 8V.

The CS8191 has a higher torque
output and better output signal
symmetry than other competitive
parts (CS289, and LM1819). It is
protected against short circuit and
overvoltage (60V) fault conditions.
