15 / 16 page AD620 REV. E –15– GROUND RETURNS FOR INPUT BIAS CURRENTS Input bias currents are those currents necessary to bias the input transistors of an amplifier. There must be a direct return path for these currents; therefore, when amplifying “floating” input VOUT AD620 – INPUT RG TO POWER SUPPLY GROUND REFERENCE + INPUT +VS –VS LOAD Figure 42a. Ground Returns for Bias Currents with Transformer Coupled Inputs sources such as transformers, or ac-coupled sources, there must be a dc path from each input to ground as shown in Figure 42. Refer to the Instrumentation Amplifier Application Guide (free from Analog Devices) for more information regarding in amp applications. VOUT – INPUT + INPUT RG LOAD TO POWER SUPPLY GROUND REFERENCE +VS –VS AD620 Figure 42b. Ground Returns for Bias Currents with Thermocouple Inputs 100k VOUT AD620 – INPUT + INPUT RG LOAD TO POWER SUPPLY GROUND REFERENCE 100k –VS +VS Figure 42c. Ground Returns for Bias Currents with AC Coupled Inputs |
