Thank you mfb :) but if the op-amp is employed in low power scenario - employing only dc currents and voltages, the fields could be negligible. In this case how guard pin makes its usage prominent?
Hi!
I came across an IC from Analog Devices - AD549, and happened to see a pin labelled as 'Guard pin'. It is being mentioned that the pin is connected to case.
I would like to understand more on the significance of this pin - its need and how to deal with it.
Also, is guard pin's need same as...
