DESCRIPTION
The VFC110 voltage-to-frequency converter is a third-
generation VFC offering improved features and per-
formance. 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 trans-
ducers 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 capaci-
tors 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.
