A current feedback design provides a bandwidth of DC-95MHz and an unprecedented settling time of 18nsec to 0.1%. And since thermal tail has been eliminated, the KH200 can be depended upon to settle fast and solidly maintain its level. Drive capability is also impressive at 24Vpp and 100mA. Using the KH200 is as easy as adding power supplies and a gain-setting resistor. The result is reliable, consistent performance because such characteristics as bandwidth and settling time are virtually independent of gain setting. Unlike conventional op amp designs where the optimum gain bandwidth product occurs at a high gain, minimum settling time at a gain of -1, maximum slew rate at a gain of +1, et cetera, the KH200 offers predictable response at gain settings from ±1 to ±50. This, coupled with consistent performance from unit to unit with no external compensation, makes the KH200 a real time and costsaver in design and production situations alike. Minimizing settling time was a design goal of the KH200. Settling time is one of the most demanding of all op amp requirements since it is affected by the op amp’s bandwidth, gain flatness, and harmonic distortion. The result of this effort is an amplifier fast enough for the most demanding high speed D to A converters ...
