DESCRIPTION
The VFC32 voltage-to-frequency converter provides
an output frequency accurately proportional to its
input voltage. The digital open-collector frequency
output is compatible with all common logic families.
Its integrating input characteristics give the VFC32
excellent noise immunity and low nonlinearity.
Full-scale output frequency is determined by an external
capacitor and resistor and can be scaled over a
wide range. The VFC32 can also be configured as a
frequency-to-voltage converter.
The VFC32 is available in 14-pin plastic DIP, SO-14
surface-mount, and metal TO-100 packages. Commercial,
industrial, and military temperature range models
are available.
