OPA2991: OPA2991

Part Number: OPA2991

Hello Carolina,

In the vidéo Troubleshooting Tips Op Amps - CMRR video for the procedure.


If we download the document How to test CMRR on an amplifier page 6, can you explain to me that moving the supply and output voltages of the AOP correspond to moving VCM  ?

Question 2

How is the choice of the voltages V+ and V- made according to these test conditions ?

Thanks for your help
