Features
• Very High Slew Rate . . . . . . . . . . . . . . . . . . . . . . 400V/µs
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.

• Monolithic Bipolar Construction
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.
Applications
• Pulse and Video Amplifiers
• Wideband Amplifiers
• High Speed Sample-Hold Circuits
• Fast, Precise D/A Converters
