The VFC110 voltage-to-frequency converter is a third-generation VFC offering improved features and performance. These include higher frequency operation, an on-board precision 5V reference and a Disable function.

The precision 5V reference can be used for offsetting the VFC transfer function, as well as exciting transducers or bridges. The Enable pin allows several VFCs' outputs to be paralleled, multiplexed, or simply to shut off the VFC. The open-collector frequency output is TTL/CMOS-compatible. The output may be isolated by using an opto-coupler or transformer.

Internal input resistor, one-shot and integrator capacitors simplify applications circuits. These components are trimmed for a full-scale output frequency of 4MHz at 10V input. No additional components are required for many applications.

The VFC110 is packaged in plastic and ceramic 14-pin DIPs. Industrial and military temperature range gradeouts are available.
