REF02: TEMP pin

Hello,

I have a question about the TEMP pin of REF02.

The explanation of the TEMP pin has the description in page15 of the REF02 data sheet.

There is a description that recommends the OpAmp of a low bias like AD8641 to be used for here.

Is this bias current allowed up to how many pA?

Best Regards,

  • Hello,

    Thank you for your reply.

    The low bias OpAmp is expensive.

    I want to use a cheap OpAmp.

    For instance, can the OpAmp of Ib=500nA be used?

    In the datasheet of REF02(Rev.K), there is a description that recommends the OpAmp of a low bias current.

    Could you tell me a maximum bias current?

    Best Regards,

    Mr.K
