FREQUENCY-TO-VOLTAGE CONVERTER
WITH SINGLE POWER SUPPLY COMPARATOR
The Fujitsu MB4206 is a frequency-to-voltage converter with an on-chip
comparator. The MB4206 uses a charge pump driven by a positive-edge Schmitt
trigger/flip-flop input so stable operation is achieved against noise signal input.
The output of the comparator is zener-clamped to a reference voltage; thus, a
precise hysteresis output is obtained. The overall design makes the circuit fairly
tolerant of imperfections in the input waveform.
