12MHz, High Input Impedance Operational
Amplifiers

HA-2600/2605 are internally compensated bipolar
operational amplifiersthat 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 fastsettling times,makethese amplifiersideally
suited to pulse amplification designs as well as high
frequency (e.g.video) applications. Thefrequency 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.
