Hi Pawel,

What is your application? What are available rail voltages? What is the circuit gain? Is 1/f noise an factor?

Here are some suggestions. I am able to refine it further, if I have more information

OPA227

OPA1611 and OPA1622

OPA209

OPA132

TLV8801/TLV8812

LPV821

LMP7721

Please also take a look at this E2E thread.
