Youngdon Jung
Prodigy 10 points
Part Number: TL431

Hello.

Can you provide input offset voltage, input offset current and input bias current of the op-amp inside TL431?

I need nominal value and deviation value under initial telerance and high/low temperature for worst case analysis.

waiting for your reply.

Thank you.

    Hi Youngdon 

    Input offset voltage is included in the initial accuracy spec (1% for A Grade and 0.5% for B grade, 2% standard grade). 

    Input bias current and input offset current are included in the IREF spec.  You can account these in your budget. 

    Regards
