Utilizing a n 0.05% settling in 15ns current feedback architecture, the KH232 offers high n 3000V/s slew rate speed performance while maintaining DC precision. n 1mV input offset voltage, 10V/C drift n 10V, 100mA max output The KH232 offers precise gains from 1 to 5 with a n Direct replacement for CLC232 true 0.1% linearity and provides stable, oscillation- free operation across the entire gain range without external compensation. The KH232, a pin compatible Applications enhanced version of the KH231, reduces 2nd and 3rd n Flash A/D drivers harmonic distortion to an extremely low -69dBc at n DAC current-to-voltage conversion 20MHz (2V , R = 100). Additional features provided pp L n Wide dynamic range IF amps by the KH232 include a small signal bandwidth of n VCO drivers 270MHz, a large signal bandwidth of 95MHz and a n DDS postamps 3000V/s slew rate. The input offset voltage is typically n Radar/communication receivers 1mV with an input offset drift of 10V/C. n Precision line drivers 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.
