CIRCUIT FUNCTION AND BENEFITS

This design solution is optimized for high precision and low cost, and it uses only five active devices. The circuit has a total error of less than 1% FSR after calibration. The small footprints of all the components make the circuit ideal for applications where printed circuit board PCB real estate is a premium. The digital output of the circuit is fully isolated therefore, the ground loop interference is eliminated, making it ideal for harsh industrial environments.

The circuit shown in Figure 1 provides a complete, robust data acquisition solution for processing conductivity cell outputs, including temperature correction. This circuit is ideal for measuring the ionic content of liquids, water quality analysis, and chemical analysis.
