Hello as part of my bachelorthesis i am working on a setpoint controller for the temperature. therefore i used the ad8497. But the amplifier is not working properly. Because the sensor has 3 states. One state for off which means 0V and one state for on 5V. But after it turns off and then again it wants to turn on it doesnt go to 5V. Instead it remains in 2.5V. Is this some kind of undocumented feature or do someone know how it can be resolved? I have two potentiometers for setting the setpoint voltage and for setting the hysteresis. so the setpoint voltage is generated by a voltage divider with a poti. I know the setpoint voltage should be generated trough a buffer. Is this the problem causing this weird behauvior? Please i need help.
