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 • VR
• Positive edge-triggered frequency input
• Equal internal reference high-level ouput and comparator high level

NOTE:
Permanent device damage may occur if the above Absolute Maximum
Ratings are exceeded. Functional operation should be restricted to the
conditions as detailed in the operational sections of this data sheet.
Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
