INA2133: Open Loop Gain Data or Plot

JP

Part Number: INA2133

Hi Team,

Do we have any internal data or information on the Open loop gain of the INA2133?

My customer was looking at this device and they didn't see this represented in the datasheet. 

Thanks,

JP

    Hello JP, 

    I am currently looking into this and will respond within 1 business day.

    Hello JP, 

    We have limited information on this specification given the age of the device. I am still investigating our resources in an attempt to gather this information. The INA21333 is a custom design so I am unable to point to a core Op amp for this spec. The spice model only models the closed loop gain of the device. We would like to understand the application circuit as well to see if there might be an alternative to the Aol specification to assist with application. Can you provide us with more information on the application circuit? I will continue to look through our resources in the mean time for the open loop gain.

    Best Regards,

    Hi Chris, 

    Given that this is for a defense application, it may be tough to understand the application circuit in detail but I've requested that info from the engineer. 

    In the meantime, please keep me posted if you find anything on the AOL. 

    Thanks,

    JP
