www.cadeka.com KH220 Fast Settling Wideband Op Amp Features I I I I I I General Description The KH220 is a wide bandwidth DC-coupled operational amplifier that defines the state-of-the-art in high speed op amps. 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. The wide bandwidth, DC coupling, and fast settling lend themselves well to high speed D to A and “flash” A to D applications. Both receivers and transmitters in optical fiber systems have similar requirements. High gain and phase linearity and corresponding low distortion make the KH220 ideal for many digital communication system applications, such as in the demodulator, where the need for both DC coupling and high frequency amplification creates requirements that are difficult to meet. The KH220 is constructed using thin film resistor/bipolar transistor technology, and available in these versions: -3dB bandwidth of 190MHz 0.1% settling in 8ns 7000V/µs slew rate 1.9ns rise and fall times Low distortion, linear phase Direct replacement for CLC220 Applications I I I I I Very high-speed A to D, D to A conversion High-speed fiber optic systems Baseband and video communications Radar and IF processors Very fast risetime pulse amplifiers Bottom View Typical Performance KH220AI KH220AK KH220AM -25°C to +85°C -55°C to +125°C -55°C to +125°C KH220HXC KH220HXA -55°C to +125°C -55°C to +125°C 12-pin TO-8 can 12-pin TO-8 can, features burn-in & hermetic testing 12-pin TO-8 can, environmentally screened and electrically tested to MIL-STD-883 SMD#: 5962-8991101HXC SMD#: 5962-8991101HXA REV. 1A January 2004 DATA SHEET KH220 KH220 Electrical Characteristics (Av = +20,Vcc = ±15V, RL = 200Ω, Rf = 1500Ω; unless specified) Min/max ratings are based on product characterization and simulation.
