HA-2542
Data Sheet October 1999 File Number 2899.3
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). For a lower power version of this product, please see the HA-2842 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 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.
