HFA1150
March 2000
File Number 4836
700MHz, SOT-23, Low Distortion Current
Feedback Operational Amplifier
The HFA1150 is a high-speed, wideband, fast settling op
amp built with Intersil's proprietary complementary bipolar
UHF-1 process. The current feedback architecture delivers
superb bandwidth even at very high gains (>300MHz at
AV = 10), and the low distortion and excellent video
parameters make this amplifier ideal for communication and
professional video applications.
Though specified for ±5V operation, the HFA1150 operates
with single supply voltages as low as 4.5V, and requires only
3.4mA of Icc in 5V applications (see Application Information
section, and Application Note AN9891).
For a lower power amplifier in a SOT-23 package, please
refer to the HFA1155 data sheet.

PC Board Layout
The frequency response of this amplifier depends greatly on
the amount of care taken in designing the PC board. The
use of low inductance components such as chip
resistors and chip capacitors is strongly recommended,
while a solid ground plane is a must!
Attention should be given to decoupling the power supplies.
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 in series with the output.
Care must also be taken to minimize the capacitance to ground
seen by the amplifier’s inverting input. The larger this
capacitance, the worse the gain peaking, resulting in pulse
overshoot and eventual instability. To reduce this capacitance,
remove the ground plane under traces connected to -IN and
keep these traces as short as possible.
Examples of good high frequency layouts are the evaluation
boards shown below.
Evaluation Boards
The performance of the HFA1150IB (SOIC) may be
evaluated using the HFA11XX Evaluation Board and a SOIC
to DIP adaptor like the Aries Electronics Part Number
08-350000-10. The SOT-23 version can be evaluated using
the OPAMPSOT23EVAL board.
To order evaluation boards (part number HFA11XXEVAL or
OPAMPSOT23EVAL), please contact your local sales office.
