Features, Applications

The Intersil 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 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 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. For a lower power version of this product, please see the HA-2850 datasheet.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES: 1. Maximum power dissipation with load conditions must be designed to maintain the maximum junction temperature below 175oC for the ceramic package, and below 150oC for the plastic package. By using Application Note AN556 on Safe Operating Area Equations, along with the thermal resistances, proper load conditions can be determined. Heat sinking is recommended above JA is measured with the component mounted on an evaluation PC board in free air.

Vertical Scale: Input = 10mV/Div.; Output = 50mV/Div. Horizontal Scale: 20ns/Div. SMALL SIGNAL RESPONSE

14. Load Capacitance should be less than 10pF. Turn on time delay typically It is recommended that resistors be carbon composition and the feedback and summing network ratios be matched to 0.1%.

16. SETTLE POINT (Summing Node) capacitance should be less than 10pF. For optimum settling time results, it is recommended that the test circuit be constructed directly onto the device pins. A Tektronix 568 Sampling Oscilloscope with S-3A sampling heads is recommended as a settle point monitor.
