1 HA-22, HA-22 Data Sheet August, 2 FN MHz, High Slew Rate, Uncompensated, High Input Impedance, Operational Amplifiers HA-22/22 comprise a series of operational amplifiers delivering an unsurpassed combination of specifications for slew rate, bandwidth and settling time. These dielectrically isolated amplifiers are controlled at close loop gains greater than 3 without external compensation. In addition, these high performance components also provide low offset current and high input impedance. 2V/µs slew rate and 2ns (.2%) settling time of these amplifiers make them ideal components for pulse amplification and data acquisition designs. These devices are valuable components for RF and video circuitry requiring up to 2MHz gain bandwidth and 2MHz power bandwidth. For accurate signal conditioning designs the HA-22/22 s superior dynamic specifications are complemented by na offset current, MΩ input impedance and offset trim capability.
