FREQUENCY OUTPUT MULTIPLIER
The AD652 can serve as a frequency output multiplier when
used in conjunction with a standard voltage-to-frequency
converter. Figure 23 shows the low cost AD654 VFC being used
as the clock input to the AD652. Also shown is a second AD652
in the F/V mode. The AD654 is set up to produce an output
frequency of 0 kHz to 500 kHz for an input voltage (V
of 0 V to 10 V. The use of R4, C1, and the XOR gate doubles this
output frequency from 0 kHz–500 kHz to 0 MHz–1 MHz.

This 1 MHz full-scale frequency is then used as the clock input
to the AD652 SVFC. Because the AD652 full-scale output
frequency is one-half the clock frequency, the 1 MHz FS clock
frequency establishes a 500 kHz maximum output frequency for
the AD652 when its input voltage (V
fore has an output frequency range from 0 kHz to 500 kHz,
which is proportional to the product of V
