HA-2540
Data Sheet September 1998 File Number 2897.3
400MHz, Fast Settling Operational
Amplifier
The Intersil HA-2540 is a wideband, very high slew rate,
monolithic operationalamplifierfeaturingsuperiorspeed 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 gainbandwidth 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.

device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Maximumpower dissipation with load conditions mustbe designed to maintain themaximum junction temperature below 175oC forthe ceramic
package, and below150oC for theplastic package. By using Application Note AN556on Safe Operating Area Equations, along withthe thermal
resistances, proper load conditions can be determined. Heat sinking is recommended above 75oC.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
