General Description

The KH205 is a wideband overdrive-protected operational amplifier designed for applications needing both speed and low power operation. Utilizing a well-established current feedback architecture, the KH205 exhibits performance far beyond that of conventional voltage feedback op amps. For example, the KH205 has a bandwidth of 170MHz at a gain of +20 and settles to 0.1 in 22ns. Plus, the KH205 has a combination of important features not found in other high-speed op amps.
