Operational Amplifier Topologies and DC Specifications
error of a. particular amplifier may or may not be a problem,. dependent on the application circuit. For instance, if a. device is configured as a buffer (also known as a volt-. age follower), amplifiers with larger offset voltage. errors, in the range of 2mV to 10mV, are usually not sig-. nificantly
