www.cadeka.com KH207 Low Distortion Wideband Op Amp Features s s s s s s s s General Description The KH207 is a wideband, low distortion operational amplifier designed specifically for applications requiring both high speed and wide dynamic range. Utilizing a proprietary current feedback architecture, the KH207 offers performance far superior to that of conventional voltage feedback op amps. The most attractive feature of the KH207 is its extremely low distortion: -80/-85dBc 2nd/3rd harmonics at 20MHz (2Vpp, RL = 200Ω). The KH207 also provides -3dB bandwidth of 170MHz at a gain of +20, settles to 0.1% in 22ns and slews at a rate of 2400V/µs. The combination of these features positions the KH207 as the right choice for high speed applications requiring exceptional signal purity. High speed, high resolution A/D and D/A converter systems requiring low distortion operation will find the KH207 an excellent choice. Wide dynamic range systems such as radar and communication receivers will find that the KH207’s low harmonic distortion and low noise make it an attractive high speed solution. The addition of the KH207 to the KH205/206 Series of high speed operational amplifiers broadens the selection of features available from which to choose. The KH205 offers low power operation, the KH206 offers higher drive operation, and the KH207 offers operation with extremely low distortion, all of which are pin compatible and overdrive protected. The KH207 is constructed using thin film resistor/bipolar transistor technology, and is available in the following versions: KH207AI KH207AK Supply Voltage -VCC 10 9 Collector Supply Output -80/-85dBc 2nd/3rd HD at 20MHz -3dB bandwidth of 170MHz 0.1% settling in 22ns Complete overdrive protection 2400V/µs slew rate 3MΩ input resistance Output may be current limited Direct replacement for CLC207 Applications s s s s s s Fast, precision A/D conversion Automatic test equipment Input/output amplifiers Photodiode, CCD preamps High-speed modems, radios Line drivers Bottom View Internal Feedback Case ground GND 7 Rf 8 -VCC -25°C to +85°C -55°C to +125°C -55°C to +125°C KH207AM 2000Ω Non-Inverting Input Inverting Input Not Connected V+ 6 + V- 5 NC 4 3 2 NC 6 6 - 11 Vo 12 +VCC Collector Supply KH207HXC KH207HXA -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#: 5962-9097701HXC SMD#: 5962-9097701HXA 1 +VCC Supply Voltage Case and bias ground GND Typical Performance Gain Setting Parameter +7 +20 +50 -1 -20 -50 Units MHz ns V/ns ns -3dB bandwidth 220 170 80 220 130 80 rise time 1.7 2.2 4.7 1.7 2.9 4.7 slew rate 2.4 2.4 2.4 2.4 2.4 2.4 settling time (to 0.1%) 22 22 20 21 20 19 Not Connected Pin 8 provides access to a 2000Ω feedback resistor which can be connected to the output or left open if an external feedback resistor is desired.
