HA-2605

HA-2600, HA-2605 September 1998 File Number 2902.3 12MHz, High Input Impedance Operational Amplifiers HA-2600/2605 are internally compensated bipolar operational amplifiers that feature very high input impedance (500MΩ, HA-2600) coupled with wideband AC performance. The high resistance of the input stage is complemented by low offset voltage (0.5mV, HA-2600) and low bias and offset current (1nA, HA-2600) to facilitate accurate signal processing. Input offset can be reduced further by means of an external nulling potentiometer. 12MHz unity gainbandwidth, 7V/µs slew rate and 150kV/V open-loop gain enables HA-2600/2605 to perform high-gain amplification of fast, wideband signals. These dynamic characteristics, coupled with fast settling times, make these amplifiers ideally suited to pulse amplification designs as well as high frequency (e.g. video) applications. The frequency response of the amplifier can be tailored to exact design requirements by means of an external bandwidth control capacitor. In addition to its application in pulse and video amplifier designs, HA-2600/2605 are particularly suited to other high performance designs such as high-gain low distortion audio amplifiers, high-Q and wideband active filters and highspeed comparators. For more information, please refer to Application Note AN515. The HA-2600 is offered as /883 Military Grade; product and data sheet are available upon request.
