QWhat is ADG702 used for?
AThe ADG702 is used for both RTD and thermocouple measurement.
When processing the signal from RTD, the ADG702 would open to break the
internal loop of AD8603. The AD8603 RTD would generate a current source to
When processing the signal from thermocouple, the ADG702 would close the
internal loop of AD8603 to generate a buffer circuit providing common-mode
voltage for thermocouple.
