OPA2991: Is OPA2991 the best Pin2Pin substitute for AD8642?

Part Number: OPA2991
Other Parts Discussed in Thread: OPA4990, OPA4991, LMC6032

Hi TIer

My customer is looking forward to AD8643's substitute.

I find OPA2991 is the best pin2pin substitute IC . Is this right? or we have new IC.

But the IBias is 10pA, AD8642 is 0.5pA

Do we have more suitable IC ?

Thank you
