ad8138 fully differential amplifier as a transimpedance amplifier

Hi,

I need a differential TIA to remove noise with several Mhz frequency bandwidth.

Can i use ad8138? The parameter seems fine to me.

Does it have any other suggestion or is there any problem with this?

Thanks.

Hi Harry,

You are right. With this bias current, the output offset is almost 0.7v with 100k.

So do you have any amplifiers suggestion for the two classic TIAs?

Before i was using op470. But it is too slow for this project.

Thanks.
