There is no exact replacement. The OPA810 might be somewhat similar, but we have to know what electrical characteristics are actually required.

Hello Akihisa,

I agree that the OPA810 may work here. There is also the OPA828 that you can take a look at. Please let us know what specific requirements must be met & if external compensation is being used for AD744.

Best,

Hello Hassan-san and Clemens-san

The customer would like almost same input offset ,input bias current as AD744. They said that they tried to replace in their own board.

Thank you so much for your advice.
