100MHz, High Input Impedance, Very
Wideband, Uncompensated Operational
Ampli鏗乪rs
HA-2620/2625 are bipolar operational ampli鏗乪rs that feature
very high input impedance (500M鈩? HA-2620) coupled with
wideband AC performance. The high resistance of the input
stage is complemented by low offset voltage (0.5mV,
HA-2620) and low bias and offset current (1nA, HA-2620) to
facilitate accurate signal processing. Input offset can be
reduced further by means of an external nulling
potentiometer. The 100MHz gain bandwidth product
(HA-2620/2625 are stable for closed loop gains greater than
5), 35V/碌s slew rate and 150kV/V open loop gain enables
HA-2620/2625 to perform high gain ampli鏗乧ation of very fast,
wideband signals. These dynamic characteristics, coupled
with fast settling times, make these ampli鏗乪rs ideally suited
to pulse ampli鏗乧ation designs as well as high frequency
(e.g., video) applications. The frequency response of the
ampli鏗乪r can be tailored to exact design requirements by
means of an external bandwidth control capacitor connected
from the Comp pin to GND.
In addition to its application in pulse and video ampli鏗乪r
designs, HA-2620/2625 is particularly suited to other high
performance designs such as high-gain low distortion audio
ampli鏗乪rs, high-Q and wideband active 鏗乴ters and high-
speed comparators. For more information, please refer to
Application Notes AN509, AN519 and AN546.
The HA-2620 is offered as /883 Military Grade. MIL-STD-
883 data sheet is available upon request. Intersil AnswerFAX
