Working Principles

The MAX4274BKEUA+T is an operational amplifier that amplifies input signals with high precision. It operates by using a differential input stage followed by a gain stage and an output buffer. The differential input stage provides high common-mode rejection ratio (CMRR) and low input offset voltage, ensuring accurate amplification of small signals. The gain stage amplifies the differential input signal, while the output buffer provides a rail-to-rail output swing. This allows the amplifier to accurately reproduce signals close to the supply voltage limits.
