850MHz, Low Distortion, Output Limiting,
Programmable Gain, Buffer Amplifier
Features
• User Programmable Output Voltage Limiting
The HFA1113 is a high speed Buffer featuring user
• User Programmable For Closed-Loop Gains of +1, -1 or
+2 Without Use of External Resistors
programmable gain and output limiting coupled with ultra
high speed performance. This buffer is the ideal choice for
high frequency applications requiring output limiting,
especially those needing ultra fast overload recovery times.
The output limiting function allows the designer to set the
maximum positive and negative output levels, thereby
protecting later stages from damage or input saturation. The
sub-nanosecond overdrive recovery time quickly returns the
amplifier to linear operation following an overdrive condition.

• Overdrive Recovery . . . . . . . . . . . . . . . . . . . . . . . . . <1ns
• Standard Operational Amplifier Pinout
A unique feature of the pinout allows the user to select a
voltage gain of +1, -1, or +2, without the use of any external
components, as described in the “Application Information”
section. Compatibility with existing op amp pinouts provides
flexibility to upgrade low gain amplifiers, while decreasing
component count. Unlike most buffers, the standard pinout
provides an upgrade path should a higher closed loop gain
be needed at a future date.
• Pb-Free Plus Anneal Available (RoHS Compliant)
Component and composite video systems will also benefit
from this buffer’s performance, as indicated by the excellent
gain flatness, and 0.02%/0.04 Degree Differential
Applications
• RF/IF Processors
• Driving Flash A/D Converters
• High-Speed Communications

The HFA1113 features a novel design which allows the user
to select from three closed loop gains, without any external

combinations for the optimum bandwidth, stability, and
settling time, but experimental fine tuning is recommended.
Picking a point above or to the right of the curve yields an
overdamped response, while points below or left of the curve
indicate areas of underdamped performance.
This “buffer” operates in closed loop gains of -1, +1, or +2,
and gain selection is accomplished via connections to the
±Inputs. Applying the input signal to +IN and floating -IN
selects a gain of +1, while grounding -IN selects a gain of
+2. A gain of -1 is obtained by applying the input signal to
-IN with +IN grounded.

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

LOAD CAPACITANCE (pF)
Terminated microstrip signal lines are recommended at the
input and output of the device. Capacitance directly on the
output must be minimized, or isolated as discussed in the
next section.
FIGURE 1. RECOMMENDED SERIES RESISTOR vs LOAD
CAPACITANCE
For unity gain applications, care must also be taken to
minimize the capacitance to ground seen by the amplifier’s
inverting input. At higher frequencies this capacitance will
tend to short the -INPUT to GND, resulting in a closed loop
gain which increases with frequency. This will cause
excessive high frequency peaking and potentially other
problems as well.
Evaluation Board
The performance of the HFA1113 may be evaluated using
the HFA11XX Evaluation Board, slightly modified as follows:
1. Remove the 500Ω feedback resistor (R ), and leave the
2
connection open.
2. a. For A = +1 evaluation, remove the 500Ω gain setting
V
resistor (R ), and leave pin 2 floating.

An example of a good high frequency layout is the
Evaluation Board shown in Figure 3.
b. For A = +2, replace the 500Ω gain setting resistor with
V
a 0Ω resistor to GND.
The modified schematic and layout of the board are shown in
Figures 2 and 3.
Driving Capacitive Loads
Capacitive loads, such as an A/D input, or an improperly
terminated transmission line will degrade the amplifier’s
phase margin resulting in frequency response peaking and
possible oscillations. In most cases, the oscillation can be

HFA1113 could be limited to ECL output levels by setting

the same voltage (GND for instance) but the result won’t be
in a DC output voltage from an AC input signal. A
Clamp Accuracy
The clamped output voltage will not be exactly equal to the

mismatches, necessitate a clamp accuracy parameter which
is found in the device specifications. Clamp accuracy is a
function of the clamping conditions. Referring again to
Figure 4, it can be seen that one component of clamp
accuracy is the VBE mismatch between the Q transistors,
and the Q transistors. If the transistors always ran at the

150mV - 200mV AC signal will still be present at the output.
Recovery from Overdrive

The output voltage remains at the clamp level as long as the
overdrive condition remains. When the input voltage drops

contribution to the inaccuracy. The Q transistors are

Overdrive Recovery Time, is required for this resumption of
linear operation. The plots of “Unclamped Performance” and
“Clamped Performance” (Figures 41 and 42) highlight the
HFA1113’s subnanosecond recovery time. The difference
between the unclamped and clamped propagation delays is
the overdrive recovery time. The appropriate propagation
delays are 8.0ns for the unclamped pulse, and 8.8ns for the
clamped (2X overdrive) pulse yielding an overdrive recovery
time of 800ps. The measurement uses the 90% point of the
output transition to ensure that linear operation has
biased at a constant current, but as described earlier, the
current through Q is equivalent to I

the true HFA1113 propagation delay is 500ps.
Overdrive recovery time is also a function of the overdrive
level. Figure 47 details the overdrive recovery time for
various clamp and overdrive levels.

usable ranges that cross 0V. While V must be more positive
