www.cadeka.com KH206 Overdrive-Protected Wideband Op Amp Features I I I I I I I I General Description The KH206 is a wideband, overdrive-protected operational amplifier designed for applications needing both speed and high drive capability (100mA). Utilizing a well-established current feedback architecture, the KH206 exhibits performance far beyond that of conventional voltage feedback op amps. For example, the KH206 has a bandwidth of 180MHz at a gain of +20 and settles to 0.1% in 19ns. Plus, the KH206 has a combination of important features not found in other high-speed op amps. The 100mA output current and the large signal bandwidth of 70MHz (20Vpp) make the KH206 ideal for applications which involve both high signal amplitudes and heavy loads as in coaxial line driving applications. Complete overdrive protection has been designed into the KH206. This is critical for applications, such as ATE and instrumentation, which require protection from signal levels high enough to cause saturation of the amplifier. This feature allows the output of the op amp to be protected against short circuits using techniques developed for low-speed op amps. With this capability, even the fastest signal sources can feature effective short circuit protection. The KH206 is constructed using thin film resistor/bipolar transistor technology, and is available in the following versions: KH206AI KH206AK -25°C to +85°C -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#: 5962-8985801HXC SMD#: 5962-8985801HXA -3dB bandwidth of 180MHz 70MHz large signal bandwidth (20Vpp) 0.1% settling in 19ns Overdrive protected Output may be current limited Stable without compensation 3MΩ input impedance Direct replacement for CLC206 Applications I I I I I I Fast, precision A/D conversion Automatic test equipment Input/output amplifiers Photodiode, CCD preamps High-speed modems, radios Line drivers Bottom View KH206AM KH206HXC KH206HXA -55°C to +125°C -55°C to +125°C Typical Performance REV. 1A January 2004 DATA SHEET KH206 KH206 Electrical Characteristics (Av = +20,Vcc = ±15V, RL = 200Ω, Rf = 2kΩ; unless specified) Min/max ratings are based on product characterization and simulation.
