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.
