A -3dB bandwidth of DC to 190MHz is achieved using a current feedback architecture design. Ultra-fast settling time (8nsec to 0.1%) and slew rate (7000V/µsec) make the KH220 a superior amplifier for pulsed and digital applications. Since thermal tail has been eliminated, the KH220 settles fast and remains solidly at the desired level. Flat gain and linear phase (1.2° deviation from linear) from DC to beyond 100MHz help the KH220 to achieve distortion levels uncommonly low relative to conventional op amps. Using the KH220 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 KH220 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 KH220 a real time and costsaver in design and production situations alike. This combination of features makes the KH220 appropriate for a broad range of applications. ...
