Part Number: OPA211

Dear Team,

                     I ordered OPA211AIDR in this part marking is OPA211A but I receiving OPA211K.

What is the difference between marking the part of OPA211A and OPA211K.

Best regards,

Muthu

    Hi Muthu,

    The OPA211AIDR is the high-grade device. When you view the device with pin 1 in the lower left corner you should see an "A" near the upper left corner indicating an A-grade device. The "K" after the "211" has a meaning that pertains to TI's internal manufacturing. A standard grade OPA211IDR may have this same "K" code marked on it. 

    If the device is marked as I have described you have received the correct device.

    Regards, Thomas
