WebAug 2, 2024 · A standard op-amp architecture consists of three interconnected subcircuits: a differential input stage, a high-gain stage, and an output stage. The input stage of the 741 … WebJan 9, 2008 · The primary motivation for using a differential pair as the input stage of an amplifier is usually its low DC offset. ... Power amp design can live with a restricted common-mode range in the input stage that would be unusable in an op-amp, and this gives the designer great scope. Complexity in itself is not a serious disadvantage as the small ... An ideal op amp is usually considered to have the following characteristics: • Infinite open-loop gain G = vout / vin • Infinite input impedance Rin, and so zero input current • Zero input offset voltage bnb thionville
