www.cadeka.com KH232 Low Distortion Wideband Op Amp Features s s s s s s s General Description The KH232 is a wideband low distortion operational amplifier designed specifically for high speed, low gain applications requiring wide dynamic range. Utilizing a current feedback architecture, the KH232 offers high speed performance while maintaining DC precision. The KH232 offers precise gains from ±1 to ±5 with a true 0.1% linearity and provides stable, oscillationfree operation across the entire gain range without external compensation. The KH232, a pin compatible enhanced version of the KH231, reduces 2nd and 3rd harmonic distortion to an extremely low -69dBc at 20MHz (2Vpp, RL = 100Ω). Additional features provided by the KH232 include a small signal bandwidth of 270MHz, a large signal bandwidth of 95MHz and a 3000V/µs slew rate. The input offset voltage is typically 1mV with an input offset drift of 10µV/°C. The KH232 combines these high performance features with its 0.05% settling time of 15ns and its 100mA drive capability to provide high speed, high resolution A/D and D/A converter systems with an attractive solution for driving and buffering. Wide dynamic range systems such as radar and communication receivers requiring low harmonic distortion and low noise will find the KH232 to be an excellent choice. As a line driver, the KH232 set at a gain of 2 cancels matched line losses. The KH232 is constructed using thin film resistor/bipolar transistor technology, and is available in the following versions: Supply Voltage -69dBc 2nd and 3rd harmonics at 20MHz -3dB bandwidth of 270MHz 0.05% settling in 15ns 3000V/µs slew rate 1mV input offset voltage, 10µV/°C drift ±10V, 100mA max output Direct replacement for CLC232 Applications s s s s s s s Flash A/D drivers DAC current-to-voltage conversion Wide dynamic range IF amps VCO drivers DDS postamps Radar/communication receivers Precision line drivers Bottom View ICC Adjust Case ground GND 7 Adjust -VCC 8 9 -VCC V+ 6 10 Collector Supply Output KH232AI KH232AK KH232AM -25°C to +85°C -55°C to +125°C -55°C to +125°C Non-Inverting Input Inverting Input Not Connected + V- 5 NC 4 3 Case ground GND 2 4 4 - 11 Vo 12 +VCC Collector Supply 1 Supply Voltage KH232HXC KH232HXA -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#: 5962-9166501HXC SMD#: 5962-9166501HXA Adjust +VCC ICC Adjust Typical Performance Gain Setting Parameter 1 2 5 -1 -2 -5 Units MHz ns V/ns ns -3dB bandwidth 430 270 135 220 175 110 rise time (2V) 1.8 2.0 2.5 2.0 2.2 2.9 slew rate 2.5 3.0 3.0 3.0 3.0 3.0 settling time (to 0.1%) 12 12 12 12 12 15 Pins 2 and 8 are used to adjust the supply current or to adjust the offset voltage (see text).
