In the design of the KH103 special care was taken in order to guarantee that the output settle quickly to within 0.4% of the final value for use with ultra fast flash A to D converters. This is one of the most demanding of all op amp requirements since settling time is affected by the op amps bandwidth, passband gain flatness, and harmonic distortion. This high degree of performance ensures excellent performance in many other demanding applications as well. The dynamic performance of the KH103 is based on a current feedback topology that provides performance far beyond that available from conventional op amp designs. Unlike conventional op amps where optimum gain-bandwidth product occurs at a high gain, minimum settling time at a gain of -1, and maximum slew rate at a gain of +1, the KH103 provides consistent predictable performance across its entire gain range. For example, the table below shows how the -3dB bandwidth remain nearly constant over a wide range of gains.
