HA-2541

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.
