DESCRIPTION
The VFC110 voltage-to-frequency converter is a thirdgeneration 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.
