www.fairchildsemi.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...
