VFC110
SBVS021A -OCTOBER 1988 -REVISED APRIL 2007 High-Frequency
VOLTAGE-TO-FREQUENCY CONVERTER
FEATURES DESCRIPTION D HIGH-FREQUENCY OPERATION:
D The VFC110 voltage-to-frequency converter is a
third-generation VFC offering improved features and
performance. These include higher frequency operation,
an onboard precision 5V reference, and a Disable
function. 4MHz FS max
EXCELLENT LINEARITY:
В±0.02% typ at 2MHz
PRECISION 5V REFERENCE
DISABLE PIN D

D LOW JITTER 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. APPLICATIONS
