Other Parts Discussed in Thread: OPA2544
In the datasheet on output protection, it says we need to protect the output voltage going beyond supply voltage by using Schottky diode. Is there a tolerance level for the output voltage, for example if I have +11.5V supply rail for opamp, due external condition like lightning in this case, voltage may exceed 11.5V, we are using diode as recommended but it will add some forward voltage drop based on current and will not be exactly 11.5V (as in ckt exapmle below). Considering this is there a + tolerance limit? How it is captured for OPA2541 device datasheet (+2V tolerance) ?
Thank you!
