APPLICATION NOTE 717
Operational Amplifier Inputs
Abstract: When does input bias current become a concern? Which architecture offers the lowest offset voltage?
This application note introduces common op-amp input structures with their associated design advantages and
challenges.
Operational amplifier (op amp) inputs vary widely in structure and performance. This document presents
common op-amp input structures. By using the Electrical Characteristics table, the op amps are identified by
type and part number.
Each op amp structure type offers its own advantages and disadvantages. Therefore, Maxim will continue to
introdu……
