70MHz, High Slew Rate, High Output
Current Operational Amplifier
The HA-2542 is a wideband, high slew rate, monolithic
operational amplifier featuring an outstanding combination of
speed, bandwidth, and output drive capability.
Utilizing the advantages of the Intersil D.I. technology this
amplifier offers 350V/µs slew rate, 70MHz gain bandwidth,
and ±100mA output current. Application of this device is
further enhanced through stable operation down to closed
loop gains of 2.
For additional flexibility, offset null and frequency
compensation controls are included in the HA-2542 pinout.
The capabilities of the HA-2542 are ideally suited for high
speed coaxial cable driver circuits where low gain and high
output drive requirements are necessary. With 5.5MHz full
power bandwidth, this amplifier is most suitable for high
frequency signal conditioning circuits and pulse video
amplifiers. Other applications utilizing the HA-2542
advantages include wideband amplifiers and fast samplehold circuits.
For more information on the HA-2542, please refer to
Application Note AN552 (Using the HA-2542), or Application
Note AN556 (Thermal Safe-Operating-Areas for High
Current Op Amps).
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 ceramic
packages, and below 150oC for plastic packages. By using Application Note AN556 on Safe Operating Area equations, along with the thermal
resistances, proper load conditions can be determined. Heatsinking will be required in many applications. See the “Application Information”
section to determine if heat sinking is required for your application.
2. θJA is measured with the component mounted on an evaluation PC board in free air.

NOTES:
3. RL = 50Ω, VO = ±5V, Output duty cycle must be reduced for I
4. Full Power Bandwidth guaranteed based on slew rate measurement using:.
> 50mA (e.g. ≤50% duty cycle for 100mA).

15. For 0.01% settling time, heat sinking is suggested to reduce
thermal effects and an analog ground plane with supply
decoupling is suggested to minimize ground loop errors.
