Intersil Corporation HA-2544 Datasheet

HA-2544

Data Sheet April 1999

50MHz, Video Operational Amplifier

The HA-2544 is a fast, unity gain stable, monolithic op amp
designed to meet the needs required for accurate
reproduction of video or high speed signals. It offers high
voltage gain (6kV/V) and high phase margin (65 degrees)
while maintaining tight gain flatness over the video
bandwidth. Built from high quality Dielectric Isolation, the
HA-2544 is another addition to the Intersil series of high
speed, wideband op amps, and offers true video
performance combined with the versatility of an op amp.

The primary features of the HA-2544 include 50MHz Gain
Bandwidth, 150V/µs slew rate, 0.03% differential gain error
and gain flatness of just 0.12dB at 10MHz. High
performance and low power requirements are met with a
supply current of only 10mA.

Uses of the HA-2544 range from video test equipment,
guidance systems, radar displaysandotherpreciseimaging
systems where stringent gain and phase requirements have
previously been met with costly hybrids and discrete
circuitry. The HA-2544 will also be used in non-video
systems requiring high speed signal conditioning such as
data acquisition systems, medical electronics, specialized
instrumentation and communication systems.

Military (/883) product and data sheets are available upon
request.

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. To achieve optimum AC performance, the input stagewas designedwithout protective diode clamps. Exceeding the maximum differential input
voltage results in reverse breakdown of the base-emitter junction of the input transistors and probable degradation of the input parameters
especially VOS, IOS and Noise.

2. θJA is measured with the component mounted on an evaluation PC board in free air.
