VFC32 В® Voltage-to-Frequency
and Frequency-to-Voltage
CONVERTER
FEATURES DESCRIPTION в—Џ OPERATION UP TO 500kHz 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. в—Џ EXCELLENT LINEARITY
В±0.01% max at 10kHz FS
В±0.05% max at 100kHz FS
в—Џ V/F OR F/V CONVERSION
в—Џ MONOTONIC
в—Џ VOLTAGE OR CURRENT INPUT 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. APPLICATIONS 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. в—Џ INTEGRATING A/D CONVERTER
