    Hello Chris,

    Thanks for using E2E.  I am not finding any reference to LM270H, and the datasheet you indicated was not attached.  

    Please Reply with the datasheet. 

    Thank you,

    ~Leonard  

    added:  I did just find this one-page reference.  Please verify this is the device:

    Hi Chris, 

    Welcome to E2E! 

    We do not have a replacement part that is compatible with the LM270H, but we can help to find a replacement part to fit your application needs. Could you help to clarify a few items: 

    • What is the supply voltage requirements? 
    • Other key op amp specs? (Iq, Bandwidth, etc)
    • Is the gain controlled feature important for the application? 
    • Is the package requirement the metal can version or is there other package versions that are possible in the application? 

    Please let me know if you have any questions.
    Thank you!

    Best Regards,
    Ashley
