HA-2540
400MHz, Fast Settling Operational
Amplifier
The Intersil HA-2540 is a wideband, very high slew rate,
monolithic operational amplifier featuring superior speed and
bandwidth characteristics. Bipolar construction coupled with
dielectric isolation allows this truly differential device to
deliver outstanding performance in circuits where closed
loop gain is 10 or greater. Additionally, the HA-2540 has a
drive capability of
±10V into a 1k load. Other desirable
characteristics include low input voltage noise, low offset
voltage, and fast settling time.
A 400V/
s slew rate ensures high performance in video and
pulse amplification circuits, while the 400MHz gain-
bandwidth product is ideally suited for wideband signal
amplification. A settling time of 140ns also makes the
HA-2540 an excellent selection for high speed Data
Acquisition Systems.
Refer to Application Note AN541 and Application Note
AN556 for more information on High Speed Op Amp
applications.
