TI has combined a modified chopper architecture with a proprietary input to create an op-amp whose precision extends to common-mode signals anywhere within its power rails – and slightly beyond. Traditional rail-to-rail inputs use a pair of differential pairs, one p-channel (or pnp) and one n-channel (or npn), whose outputs are combined in a later ...
