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.
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). Also see ‘Applications’
