HA-2600

12MHz, High Input Impedance Operational

Amplifier

HA-2600 is an internally compensated bipolar operational

amplifier that features very high input impedance (500M

Ω)

coupled with wideband AC performance. The high

resistance of the input stage is complemented by low offset

voltage (0.5mV) and low bias and offset current (1nA) to

facilitate accurate signal processing. Input offset can be

reduced further by means of an external nulling

potentiometer. 12MHz unity gain-bandwidth, 7V/

µs slew rate

and 150kV/V open-loop gain enables the HA-2600 to

perform high-gain amplification of fast, wideband signals.

These dynamic characteristics, coupled with fast settling

times, make this amplifier 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, the HA-2600 is particularly suited to other high

performance designs such as high-gain low distortion audio

amplifiers, high-Q and wideband active filters and high-

speed comparators.
