Voltage reference | Cypress Semiconductor
I'm trying this, an operational amplifier, in non inverting mode with two 10K external resistors, the gain is 2. The non inverting input is connected to the 1,024V voltage reference. The output is 3,68V and I don't understand why, I think it must be 2,08V (voltage reference value x 2).
If I connect the voltage reference to an external pin and the non inverting input of the operational amplifier to another external pin and joint the two pins externally with a wire, it works perfectly. Somebody can tell me why?
Im very new in Psoc programming, any comment is going to be usefull for me.
