Figure 8-5. Detecting Leakage Currents

An example output response of a difference configuration is shown in Figure 8-6. The reference pin of the first

channel is connected to a reference voltage of 2.048 V. The inputs to each circuit is a 100-Hz sine wave, 180°

out-of-phase with each other, resulting in a zero output as shown. The sine wave input to the first circuit is offset

so that the input wave is completely above GND.
