Dear Comminity,
I have a probelm with one of my 2 opamp inside the LMP7702. The opamp is super-sensitive to temperature: when below 40 deg everithing is fine but when the temperature gose over 40 deg, I found the output be saturatet to the rail voltage. Consider that the other opamp in the pakage is working fine also with the temperature change.
That's my circuit
The opamp in the U506 is satuarting with the incresaing of temperature and the others that are close togherter works fine. Also the 4 DAC are working fine. In additio the risistors are all 0.1%
What happens? Can you give me an hint?
Best,
CM4
