com FUJITSU SEMICONDUCTOR DATA SHEET DS04-13400-2E LINEAR IC FREQUENCY-TO-VOLTAGE CONVERTER MB4206 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.
• Conversion coefficient determined by RC pair: VO(F) = FIN • RT • CT • ...
