Dual, 425MHz, Low Power, Video
Operational Amplifier
• Low Supply Current . . . . . . . . . . . . . . . . . 5.8mA/Op Amp

• Wide -3dB Bandwidth (AV = +2) . . . . . . . . . . . . . 425MHz
These amplifiers deliver 425MHz bandwidth and 1350V/μs
slew rate, on only 60mW of quiescent power. They are
specifically designed to meet the performance, power, and
cost requirements of high volume video applications. The
excellent gain flatness and differential gain/phase
performance make these amplifiers well suited for
component or composite video applications. Video
performance is maintained even when driving a back
terminated cable (RL = 150Ω), and degrades only slightly
when driving two back terminated cables (RL = 75Ω). RGB
applications will benefit from the high slew rates, and high
full power bandwidth.
The HFA1205 is a pin compatible, low power, high
performance upgrade for the popular Intersil HA5023. For a
dual amplifier with output disable capability, please see the
HFA1245 data sheet.

NOTES:
3. Test Level: A. Production Tested.; B. Typical or Guaranteed Limit Based on Characterization.; C. Design Typical for Information Only.
4. Undershoot dominates for output signal swings below GND (e.g., 0.5VP-P), yielding a higher overshoot limit compared to the
VOUT = 0V to 0.5V condition. See the “Application Information “section for details.
5. Slew rates are asymmetrical if the output swings below GND (e.g., a bipolar signal). Positive unipolar output signals have symmetric positive
and negative slew rates comparable to the +SR specification. See the “Application Information” text, and the pulse response graphs for details.
6. See Typical Performance Curves for more information.
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 HFA1205 design is
optimized for a 464Ω 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
4
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 for various gains, and
the expected bandwidth. For good channel-to-channel gain
matching, it is recommended that all resistors (termination
as well as gain setting) be ±1% tolerance or better. Note that
a series input resistor, on +IN, is required for a gain of +1, to
reduce gain peaking and increase stability.

HFA1205
For best operation, the DC source impedance seen by the
non-inverting input should be ≥50Ω. This is especially
important in inverting gain configurations where the noninverting input would normally be connected directly to GND.
Pulse Undershoot and Asymmetrical Slew Rates
The HFA1205 utilizes a quasi-complementary output stage
to achieve high output current while minimizing quiescent
supply current. In this approach, a composite device
replaces the traditional PNP pulldown transistor. The
composite device switches modes after crossing 0V,
resulting in added distortion for signals swinging below
ground, and an increased undershoot on the negative
portion of the output waveform (see Figures 7, 11, 15 and
19). This undershoot isn’t present for small bipolar signals,
or large positive signals (see Figures 5, 6, 9, 10, 13, 14, 17
and 18). Another artifact of the composite device is
asymmetrical slew rates for output signals with a negative
voltage component. The slew rate degrades as the output
signal crosses through 0V (see Figures 7, 11, 15, and 19),
resulting in a slower overall negative slew rate. Positive only
signals have symmetrical slew rates as illustrated in the
large signal positive pulse response graphs (see Figures 5,
9, 13 and 17).
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
(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 at the amplifier’s inverting input (-IN). The larger this
capacitance, the worse the gain peaking, resulting in pulse
overshoot and possible instability. Reduce this capacitance
by removing the ground plane under traces connected to IN, and keep connections to -IN 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.
5
Figure 1 details starting points for the selection of this
resistor. The points on the curve indicate the RS and CL
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.
RS and CL form a low pass network at the output, thus
limiting system bandwidth well below the amplifier
bandwidth of 425MHz (for AV = +2). By decreasing RS as
CL increases (as illustrated in the curves), the maximum
bandwidth is obtained without sacrificing stability. In spite
of this, bandwidth still decreases as the load capacitance
increases. For example, at AV = +2, RS = 50Ω, CL = 22pF,
the overall bandwidth is limited to 230MHz, and bandwidth
drops to 80MHz at AV = +2, RS = 7Ω, CL = 390pF.

Evaluation Board
The performance of the HFA1205 may be evaluated using
the HA5023 Evaluation Board.
The performance of the HFA1205IB (SOIC) may be
evaluated using the HA5023 Evaluation Board and a SOIC
to DIP adaptor like the Aries Electronics Part Number
08-350000-10.
The schematic for amplifier 1 and the board layout are
shown in Figure 2 and Figure 3. Resistors RF, RG and RS
may require a change to the appropriate value (see
“Optimum Feedback Resistor” section) for the gain being
evaluated.
