interface labview with the test board to identify opamp pins automatically

Hi pratheek,

could you solve your issue?

Best regards

It quit working because you let the smoke out.

I don't think anybody can.  You can't just plug a random IC into a test bed and start hitting random pins with voltages until you somehow figure out the pinout.  There are too many variables.  There are thousands of general-purpose op-amps out there.  Some can run on a single-ended 3V supply, some won't even begin to operate until they have the right positive and negative supply voltages connected (AND the ground).  Some are internally compensated, some require external components.  All will need at least a couple resistors connected to the right pins to work as an op-amp.

Bottom line is:  By the time you think you've identified the pins correctly, you've probably damaged the device somehow so why bother testing it?

OP:  Get a library of op-amps you want to test including their pinouts AND the parameter set to stimulate them AND the specifications for PASS/FAIL criteria.  Then you can code a test suite.  LabVIEW would be great for this application.

Well said!

Thanks alot for ur suggestions. There were few changes done  in my tasks finally. V+ & V- are selected manually and user can select stored device types or manual setup for pinouts

That makes much more sense. It is also much easier to implement.

I think it's just a lesson we all learn over the course of our careers:

Sometimes something makes perfect sense until you think about implementing it.
