Description

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 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.
