750MHz, Low Distortion Unity Gain,
Closed Loop Buffer
The HFA1110 is a unity gain closed loop bufferthatachieves
-3dB bandwidth of 750MHz, while offering excellent video
performance and low distortion. Manufactured on Intersil’s
proprietary complementary bipolar UHF-1 process, the
HFA1110 also offers very fast slew rate, and high output
current. It is one more example of Intersil’s intent to enhance
its leadership position in products for high speed signal
processing applications.
The HFA1110’s settling time of 11ns to 0.1%, low distortion
and ability to drive capacitive loads make it an ideal flash
A/D driver.
The HFA1110 is an enhanced, pin compatible upgrade for
the AD9620, AD9630, CLC110, EL2072, BUF600 and
BUF601.
For buffer applications requiring a standard op amp pinout,
or selectable gain (-1, +1, +2), see the HFA1112 data sheet.
For output limiting see the HFA1113 data sheet.
For military grade product please refer to the HFA1110/883
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.

SCHEMATIC DIAGRAM
A large value (10µF) tantalum in parallel with a small value
chip (0.1µF) capacitor works well in most cases.

Terminated microstrip signal lines are recommended at the
input and output of the device. Output capacitance, such as
that resulting from an improperly terminated transmission
line will degrade the frequency response of the amplifier and
may cause oscillations. In most cases, the oscillation can be
avoided by placing a resistor (R
See the “Recommended R
) in series with the output.

Evaluation Board shown below.
Evaluation Board
An evaluation board is available for the HFA1110 (part
number HFA1110EVAL). Please contact your local sales
office for information.
The layout and schematic of the board are shown here:
NOTE: The SOIC version may be evaluated in the DIP board by
using a SOIC-to-DIP adapter such as Aries Electronics Part Number
08-350000-10.
