DescriptionThe RC4152 is a monolithic circuit containing all of the
active components needed to build a complete voltage-to-
frequency converter. Circuits that convert a DC voltage to a
pulse train can be built by adding a few resistors and capaci-
tors to the internal comparator, one-shot, voltage reference,
and switched current source. Frequency-to-voltage convert-
ers (FVCs) and many other signal conditioning circuits are
also easily created using these converters.
The RC4151 was the first monolithic VFC available and
offers guaranteed temperature and accuracy specifications.
The converter is available in a standard 8-pin plastic DIP.
