opa627

Is There an equivalent for bb opa627?

  • I like the ADA4625-1, it has lower noise, especially flicker noise which is important in precision DC. It has more Ib however. For strict Ib and Vos:

    You can probably do better if you decide which of the opa627 parameters are important to you. E.g do you need the wide voltage supply range?
