Speedometer/Odometer or Tachometer Application
C
In some cases a designer may wish to use the CS8190 only
as a driver for an air-core meter having performed the F/V
conversion elsewhere in the circuit.
Figure 8 shows how to drive the CS8190 with a DC voltage
ranging from 2V to 6V. This is accomplished by forcing a
voltage on the F/V
OUT
lead. The alternative scheme shown
in Figure 9 uses an external op amp as a buffer and oper-
ates over an input voltage range of 0V to 4V.
Figure 8. Driving the CS8190 from an external DC voltage.
An alternative solution is to use the CS4101 which has a
separate function generator input lead and can be driven
directly from a DC source.

Amp Buffer.

Note 1: C2 (> 2000μF) is needed if return to zero function is required.
Note 2: The product of C4 and R4 have a direct effect on gain and
therefore directly effect temperature compensation.
Note 3: C4 Range; 20pF to .2μF.

Note 4: R4 Range; 100k to 500k.
Note 5: The IC must be protected from transients above 60V and reverse
battery conditions.
Note 6: Additional filtering on the FREQ
IN
lead may be required.
