HA-2600 is an internally compensated bipolar operational
amplifier that features very high input impedance (500MΩ)
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 highspeed
comparators.
