100MHz, High Input Impedance, Very
Wideband, Uncompensated Operational
Amplifiers
HA-2620/2625 are bipolar operational amplifiers 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 amplification of very 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 connected
from the Comp pin to GND.
In addition to its application in pulse and video amplifier
designs, HA-2620/2625 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. For more information, please refer to
Application Notes AN509, AN519 and AN546.
