4. Functionality
The MDFH110x operates by measuring the frequency of an incoming AC or pulse signal and converting it into a proportional DC voltage. The internal circuitry counts or integrates the frequency over a defined time interval, generating a corresponding analog voltage output that scales linearly with the input frequency.
Operating Principle:
1. The input signal (square, triangle, or sine wave) is fed into the converter’s input stage.
2. The signal is conditioned and shaped to ensure accurate frequency detection, regardless of waveform type.
3. The internal frequency-to-voltage conversion circuit (typically based on a charge pump or frequency integrator) produces a DC voltage proportional to the input frequency.
4. The output stage filters and stabilizes the voltage, providing a smooth 0–5 V signal suitable for analog measurement or control.
Use Cases and Applications:
- Rotational Speed Measurement: Converts tachometer or encoder frequency signals into voltage for analog speed indicators or controllers.
- Flow Measurement: Used with flow sensors that output frequency signals proportional to flow rate.
