Dear friends ,
Facing a problem that :
I am converting pt100 resistance to voltage ......using non inverting opamp amplifier configuration, using +- 5V supplies .
But the opamp o/p voltage is not reaching full 5V.....
as i increase the feed back resistor rf to increase the gain.....there comes a stage when voltage on multimeter shows 5.23 v for a fraction of sec...then the the voltage gets stuck to 4.23 volts......
please suggest what to do........
