Op Amp Specifications
Walt Kester, Walt Jung and James Bryant
In this section, basic op amp specifications are discussed. The importance of any given specification depends of course upon the application. For instance offset voltage, offset voltage drift, and open-loop gain are very critical in precision sensor signal conditioning circuits, but not as important in high speed applications where bandwidth, slew rate, and distortion are the key specifications.
Most op amp specifications are largely topology independent. However, although voltage feedback and current feedback op amps have similar error terms and specifications, the application of each part warrants discussing some of the specifications separately. In the following discussions, ...
