HA-2541
Data Sheet September 1998 File Number 2898.3
40MHz, Fast Settling, Unity Gain Stable,
Operational Amplifier
The HA-2541 is the first unity gain stable monolithic
operational amplifier to achieve 40MHz unity gain
bandwidth. A major addition to the Intersil series of high
speed, wideband op amps, the HA-2541 is designed for
video and pulse applications requiring stable amplifier
response at low closed loop gains.
The uniqueness of the HA-2541 is that its slew rate and
bandwidth characteristics are specified at unity gain.
Historically, high slew rate, wide bandwidth and unity gain
stability have been incompatible features for a monolithic
operational amplifier. But features such as 250V/µs slew rate
and 40MHz unity gain bandwidth clearly show that this is not
the case for the HA-2541. These features , along with 90ns
settling time to 0.1%, make this product an excellent choice
for high speed data acquisition systems.
MIL-STD-883 product and data sheets are available upon
request, Intersil AnswerFAX (407-724-7800) document
#3698.
For further application suggestions on the HA-2541, please
refer to Application Note AN550 (Using the HA-2541), and
Application Note AN556 (Thermal Safe Operating Areas for
High Current Operational Amplifiers), Intersil AnswerFAX
(407-724-7800) document #9550 and 9556. Also see
‘Applications’ in this data sheet.

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. 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 75oC.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
