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 1kΩ load. Other desirable

characteristics include low input voltage noise, low offset

voltage, and fast settling time.

A 400V/

µs 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. HA-2540/883 MIL-STD-883 data sheet is

available on request.
