### 4. Functionality

The MDF6002 functions as an active low-pass antialiasing filter, designed to condition analog signals before they are digitized by an analog-to-digital converter (ADC). Its primary role is to attenuate frequency components above 200 Hz, which could otherwise cause aliasing artifacts in sampled data.

Operating Principle:
- The input signal (±5 V) is fed into the filter’s differential input stage.
- The internal active filter circuitry—typically based on precision operational amplifiers and RC networks—processes the signal.
- Frequencies below the cutoff (200 Hz) pass through with minimal attenuation and phase distortion.
- Frequencies above the cutoff are progressively attenuated, ensuring that unwanted high-frequency noise or interference does not fold back into the measurement band during sampling.
- The filtered signal is then output as a ±5 V differential signal, ready for digitization or further analog processing.

Use Cases and Applications:
- Data Acquisition Systems (DAQ): Pre-filtering analog signals before ADC conversion to ensure accurate digital representation.
- Industrial Measurement: Conditioning sensor outputs such as strain gauges, pressure transducers, or temperature sensors.
- Control Systems: Filtering feedback signals in closed-loop control applications to improve stability and response.
- Audio and Vibration Analysis: Low-frequency signal conditioning for vibration, acoustic, or seismic measurements.
- Scientific Instrumentation: Precision filtering in laboratory measurement setups.

Compatibility:
- Compatible with modular instrumentation platforms using ±15 V analog power rails.
- Interfaces with standard analog I/O modules, ADC boards, and signal conditioning racks.
- Can be integrated into custom analog front-end circuits or embedded systems requiring low-frequency filtering.
