Amplifier Selection Help

Other Parts Discussed in Thread: OPA2188, OPA2180

I am looking at the LT1013I or LT1013AI.  I am fine with the input offset voltage of the LT1013I but if the LT1013AI isn’t much more expensive I would use that part.  I can’t seem to find either one on the TI website.  Or if they have an equivalent part that would be alright as well.  As of now I am looking at using the LT1013DID. The TI website states the part is -40C to 85C but the data sheet says the “I” suffix should be a -40C to 105C.  Which is correct?

    Hi Jason,

    Looking at the datasheet for the part I believe the correct temperature range for the LT1013DID is -40C to 105C. I also recommend that you look at the OPA2180 or OPA2188 as these are much newer parts that may give you a boost in performance due to their superior offset and drift and they are both spec'd over the -40 to 105C temp range.

    Hope this helps!

    Jason,

    The LT1013DID is -40C to 105C per the data sheet.
    The data sheet is the most reliable source for information.
