1-888-
450MHz, Low Power, Video Operational
Amplifier with Programmable Output
Disable
The HFA1149 is a high speed, low power, current feedback
amplifier built with Intersil’s proprietary complementary
bipolar UHF-1 process. This amplifier features a unique
combination of power and performance specifically tailored
for video applications.
The HFA1149 incorporates an output disable pin which is
TTL/CMOS compatible, and user programmable for polarity
(active high or low). This feature eliminates the inverter
required between amplifiers in multiplexer configurations.
The ultra-fast (12ns/20ns) disable/enable times make the
HFA1149 the obvious choice for pixel switching and other
high speed multiplexing applications. The HFA1149 is a high
performance, pin compatible upgrade for the popular HA-5020
and HFA1145, as well as the CLC410.
For a comparably performing op amp without an output
disable, please refer to the HFA1109 data sheet.

DESCRIPTION
Threshold Set
Optional Logic Threshold Set. Maintains disable
pin TTL compatibility with asymmetrical supplies
(e.g., +10V, 0V).
Polarity Set
Defines Polarity of Disable Input. High or floating
selects active low disable (i.e., DIS).
DIS/DIS
TTL Compatible Disable Input. Output is driven to
a true Hi-Z state when active. Polarity depends on
state of Polarity Set Pin.

HFA1149
Application Information
Optimum Feedback Resistor
Although a current feedback amplifier’s bandwidth
dependency on closed loop gain isn’t as severe as that of a
voltage feedback amplifier, there can be an appreciable
decrease in bandwidth at higher gains. This decrease may
be minimized by taking advantage of the current feedback
amplifier’s unique relationship between bandwidth and RF .
All current feedback amplifiers require a feedback resistor,
even for unity gain applications, and RF , in conjunction with
the internal compensation capacitor, sets the dominant pole
of the frequency response. Thus, the amplifier’s bandwidth is
inversely proportional to RF . The HFA1149 design is
optimized for a 250Ω RF at a gain of +2. Decreasing RF
decreases stability, resulting in excessive peaking and
overshoot (Note: Capacitive feedback will cause the same
problems due to the feedback impedance decrease at higher
frequencies). At higher gains the amplifier is more stable, so
RF can be decreased in a trade-off of stability for bandwidth.

Table 1 lists recommended RF values, and the expected
bandwidth, for various closed loop gains. For a gain of +1, a
resistor (+RS) in series with +IN is required to reduce gain
peaking and increase stability
Output Disable Function
The HFA1149 incorporates an output disable function that is
useful for reducing power dissipation or for multiplexing
signals onto a common analog bus. When disabled, the
inverting input and the output become high impedances
(however, the feedback network for gains other than +1 still
present a load to ground from the output), the supply current
reduces by 68%, and the input to output isolation becomes
greater than 60dB. The amplifier is disabled by driving the
DIS / DIS input to its active state.
The DIS / DIS input is TTL compatible, and unlike most
competitive devices, the TTL compatibility can be
maintained when the HFA1149 is operated at supplies other
than ±5V (see the “Threshold Set input” section below).
An internal resistive bias network ensures that the DIS / DIS
pin is pulled high if it is undriven on the PCB.
Polarity Set Input
A novel feature of the HFA1149 is the polarity
programmability of the disable control pin (DIS / DIS).
Depending on the state of the Polarity Set input (pin 5), the
designer can define the active state to be high or low for the
DIS / DIS input (see the “HFA1149 Disable Functionality”
table on the front page). With this feature, a 2:1 multiplexer
can be created by defining one amplifier’s disable control as
active low (Polarity Set = High or floating), and the other
amplifier’s control as active high (Polarity Set = Low). Note
that if the Polarity Set pin is left floating, an internal pull-up
resistor pulls the pin high, and the HFA1149 becomes a
drop-in replacement for any standard ±5V supply op amp
with output disable (e.g., CLC410, CLC411, CLC430,
HA-5020, HFA1145, AD810). Likewise, if the disable and
polarity set pins are both floated, the HFA1149 works just
like a standard op amp (i.e., the output is always enabled).
Threshold Set Input for TTL Compatibility
The HFA1149 derives an internal threshold reference for the
digital circuitry as long as the power supplies are nominally
±5V. This reference is used to ensure the TTL compatibility
of the DIS / DIS and Polarity Set inputs. With symmetrical
±5V supplies the Threshold Set pin (Pin 1) must be floated to
guarantee TTL compatibility. If asymmetrical supplies (e.g.,
+10V, 0V) are utilized, and TTL compatibility is desired, the
Threshold Set pin must be connected to an external voltage
(e.g., GND for +10V, 0V operation). The following equation
should be used to determine the voltage (VTHSET) to be
applied to the Threshold Set pin:
VV THSET = 1.58 ( V DIGTH + 1.6V ) – ------ – 0.46 ( V+ ),
8
where VDIGTH is the desired switching point (typically 1.4V
for TTL compatibility) of the Polarity Set and DIS / DIS
inputs.
Figure 1 illustrates the input impedance of the Threshold Set
pin for calculating the input current at a given VTHSET.
V+
The active state of the DIS / DIS input is user programmable
via the HFA1149’s Polarity Set input (see next paragraph). If
the Polarity Set input is left floating, or is tied to a logic high
(e.g., V+), then the disable function is activated by a logic
low on the DIS / DIS input (typical of most output disable op
amps). If the Polarity Set input is connected to a logic low
(e.g., GND), then a logic high on the DIS / DIS input disables
the amplifier.

BOARD SCHEMATIC
The frequency response of this amplifier depends greatly on
the 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 (0.1µF) chip capacitor
works well in most cases.
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.
Care must also be taken to minimize the capacitance to
ground seen by the amplifier’s inverting input (-IN). The
larger this capacitance, the worse the gain peaking, resulting
in pulse overshoot and possible instability. Thus, it is
recommended that the ground plane be removed under
traces connected to -IN, and connections to -IN should be
kept as short as possible.
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
avoided by placing a resistor (RS) in series with the output
prior to the capacitance.

RS and CL form a low pass network at the output, thus
limiting system bandwidth well below the amplifier
bandwidth. By decreasing RS as CL increases, the
maximum bandwidth is obtained without sacrificing stability.
In spite of this, bandwidth still decreases as the load
capacitance increases.
Evaluation Board
The performance of the HFA1149 may be evaluated using
the HFA11XX Evaluation Board (part number
HFA11XXEVAL). Please contact your local sales office for
information. When evaluating this amplifier, the two 510Ω
gain setting resistors on the evaluation board should be
changed to 250Ω.
The layout and schematic of the board are shown in Figure 2.
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.

2. Dimensioning and tolerancing per ANSI Y14.5M-1982.
3. Dimension “D” does not include mold flash, protrusions or gate burrs.
Mold flash, protrusion and gate burrs shall not exceed 0.15mm (0.006
inch) per side.
4. Dimension “E” does not include interlead flash or protrusions. Interlead flash and protrusions shall not exceed 0.25mm (0.010 inch) per
side.
5. The chamfer on the body is optional. If it is not present, a visual index
feature must be located within the crosshatched area.
6. “L” is the length of terminal for soldering to a substrate.
7. “N” is the number of terminal positions.
8. Terminal numbers are shown for reference only.
9. The lead width “B”, as measured 0.36mm (0.014 inch) or greater
above the seating plane, shall not exceed a maximum value of
0.61mm (0.024 inch).
10. Controlling dimension: MILLIMETER. Converted inch dimensions
are not necessarily exact.
