DETAILS OF OPERATION, FREQUENCY-TO-
VOLTAGE CONVERTERS (
Figure 6 and Figure 7)
In these applications, a pulse input at f
IN is differentiated by
a C-R network and the negative-going edge at pin 6 causes
the input comparator to trigger the timer circuit. Just as with
a V-to-F converter, the average current flowing out of pin 1 is
I
AVERAGE = i x (1.1 RtCt)xf.
In the simple circuit of
Figure 6, this current is filtered in the
network R
L = 100 kΩ and 1 µF. The ripple will be less than 10
mV peak, but the response will be slow, with a 0.1 second
time constant, and settling of 0.7 second to 0.1% accuracy.
In the precision circuit, an operational amplifier provides a
buffered output and also acts as a 2-pole filter. The ripple will
be less than 5 mV peak for all frequencies above 1 kHz, and
the response time will be much quicker than in
Figure 6.
However, for input frequencies below 200 Hz, this circuit will
have worse ripple than
Figure 6. The engineering of the filter
time-constants to get adequate response and small enough
ripple simply requires a study of the compromises to be
made. Inherently, V-to-F converter response can be fast, but
F-to-V response can not.

*Use stable components with low temperature coefficients.
See Typical Applications section.
**This resistor can be 5 k
Ω or 10 kΩ for VS=8V to 22V, but must be 10 kΩ for VS=4.5V to 8V.
***Use low offset voltage and low offset current op amps for A1: recommended types LF411A or LF356.
