Hello,

I have a question about the Figure 86, page 317 from UG-587. Into the explanation is said "The excitation buffer forces the output voltage D to be equal to the differential voltage across the sensor, P-N". What does it give us like benefit. Can someone explain in more details the idea of these P and N feedbacks.

Thank you
