www.cadeka.com KH103 www.datasheet4u.com Fast Settling, High Current Wideband Op Amp Features s s s s s s General Description The KH103 is a high-power, wideband op amp designed for the most demanding high-speed applications. The wide bandwidth, fast settling, linear phase, and very low harmonic distortion provide the designer with the signal fidelity needed in applications such as driving flash A to Ds. The 80MHz full-power bandwidth and 200mA output current of the KH103 eliminate the need for power buffers in most applications; the KH103 is an excellent choice for driving large highspeed signals into coaxial lines. 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 rang...
