DESCRIPTION

· The VFC32 is a voltage-to-frequency converter with an output frequency proportional to its input voltage.
· It features a digital open-collector frequency output compatible with common logic families.
· Offers excellent noise immunity and low nonlinearity due to its integrating input characteristics.
· Full-scale output frequency is adjustable via external capacitor and resistor.
· Can also function as a frequency-to-voltage converter.
· Available in 14-pin plastic DIP, SO-14 surface-mount, and metal TO-100 packages.
· Models available for commercial, industrial, and military temperature ranges.

FEATURES

· Operates up to 500kHz.
· Excellent linearity: 0.01% max at 10kHz FS, 0.05% max at 100kHz FS.
· Supports V/F or F/V conversion.
· Monotonic performance.
· Accepts voltage or current input.

APPLICATIONS

· Integrating A/D converter.
· Serial frequency output.
· Isolated data transmission.
· FM analog signal modulation/demodulation.
· Motor speed control.
· Tachometer.
