Data Sheet
HA-2542
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 sample-
hold 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).

HA-2542
Application Information (Refer to Application Note AN552 for Further Information)
The Intersil HA-2542 is a state of the art monolithic device
which also approaches the “ALL-IN-ONE” amplifier concept.
This device features an outstanding set of AC parameters
augmented by excellent output drive capability providing for
suitable application in both high speed and high output drive
circuits.
Primarily intended to be used in balanced 50Ω and 75Ω
coaxial cable systems as a driver, the HA-2542 could also be
used as a power booster in audio systems as well as a
power amp in power supply circuits. This device would also
be suitable as a small DC motor driver.
The applications shown in Figures 2 through Figure 4
demonstrate the HA-2542 at gains of +100 and +2 and as a
video cable driver for small signals.
Power Dissipation Considerations
At high output currents, especially with the PDIP package,
care must be taken to ensure that the Maximum Junction
Temperature (TJ, see “Absolute Maximum Ratings” table) is
not exceeded. As an example consider the HA-2542 in the
PDIP package, with a required output current of 20mA at
VOUT = 5V. The power dissipation is the quiescent power
(1.2W = 30V x 40mA) plus the power dissipated in the
output stage (POUT = 200mW = 20mA x (15V - 5V)), or a
total of 1.4W. The thermal resistance (θJA) of the PDIP
package is 100oC/W, which increases the junction
temperature by 140oC over the ambient temperature (TA).
Remaining below TJMAX requires that TA be restricted to ≤
10oC (150oC - 140oC). Heatsinking would be required for
operation at ambient temperatures greater than 10oC.
Note that the problem isn’t as severe with the CERDIP
package due to it’s lower thermal resistance, and higher
TJMAX. Nevertheless, it is recommended that Figure 1 be
used to ensure that heat sinking is not required.

Allowable output power can be increased by decreasing the
quiescent dissipation via lower supply voltages.
For more information please refer to Application Note
AN556, “Thermal Safe Operating Areas for High Current Op
Amps”.
Prototyping Guidelines
For best overall performance in any application, it is
recommended that high frequency layout techniques be
used. This should include: 1) mounting the device through a
ground plane: 2) connecting unused pins (NC) to the ground:
3) mounting feedback components on Teflon standoffs and
or locating these components as close to the device as
possible: 4) placing power supply decoupling capacitors
from device supply pins to ground.
