3. Determine C4
C4 is selected to satisfy both the maximum allowable rip-
ple voltage and response time of the meter movement.
C4 =
With C4 = 0.47μF, the F/V ripple voltage is 44mV.
The last component to be selected is the return to zero
capacitor C2. This is selected by increasing the input sig-
nal frequency to its maximum so the pointer is at its max-
imum deflection and removing the power from the cir-
cuit. C2 should be large enough to ensure that the pointer
always returns to the 0 position rather than 360 under
all operating conditions.
Figure 7 shows how the CS8190 and the CS8441 are used
to produce a Speedometer and Odometer circuit.
