I have a problem with an instrumentation amplifier Type AD8429. I tested it now in a simply configuration, just  Power Supply, Reference tied to ground and a test Gain resistor of 1,5 KOhms. Applying a signal to the inputs in the allowed range the signal appears with the desired Gain at the output but only for a few seconds. Then the signal turns to zero. Resetting is available if I take off the power supply an apply again. This I can repeat as of as I want. But I want an constant signal. At the moment I have no solution what the problen can be...The actual state is none satisfied.
