HA5023/883
Dual 125MHz Video Current
Feedback Amplifier
Description
The HA5023/883 is a dual version of the popular Intersil
HA-5020/883 except that it does not have an enable function. It
features wide bandwidth and high slew rate, and is optimized
for video applications and gains between 1 and 10. It is a cur-
rent feedback amplifier and thus yields less bandwidth degra-
dation at high closed loop gains than voltage feedback
amplifiers.
The low differential gain and phase, 0.1dB gain flatness, and
ability to drive two back terminated 75
cables, make this
amplifier ideal for demanding video applications.
The current feedback design allows the user to take advan-
tage of the amplifier's bandwidth dependency on the feed-
back resistor. By reducing R
F
, the bandwidth can be
increased to compensate for decreases at higher closed
loop gains or heavy output loads.

NOTES:
1. Parameters listed in Table 3 are controlled via design or process parameters and are not directly tested at final production. These param-
eters are lab characterized upon initial design release, or upon design changes. These parameters are guaranteed by characterization
based upon data from multiple production runs which reflect lot-to-lot and within lot variation.
2. Measured between 10% and 90% points.
3. For 200ps input transition times. Overshoot decreases as input transition times increase, especially for A
V
= +1. Please refer to
Performance Curves.
4. Measured between 25% and 75% points.

NOTES:
1. Index area: A notch or a pin one identification mark shall be locat-
ed adjacent to pin one and shall be located within the shaded
area shown. The manufacturer's identification shall not be used
as a pin one identification mark.
2. The maximum limits of lead dimensions b and c or M shall be
measured at the centroid of the finished lead surfaces, when
solder dip or tin plate lead finish is applied.
3. Dimensions b1 and c1 apply to lead base metal only. Dimension
M applies to lead plating and finish thickness.
4. Corner leads (1, N, N/2, and N/2+1) may be configured with a
partial lead paddle. For this configuration dimension b3 replaces
dimension b2.
5. This dimension allows for off-center lid, meniscus, and glass
overrun.
6. Dimension Q shall be measured from the seating plane to the
base plane.
7. Measure dimension S1 at all four corners.
8. N is the maximum number of terminal positions.
9. Dimensioning and tolerancing per ANSI Y14.5M - 1982.
10. Controlling dimension: INCH.

HA5023
Application Information
Optimum Feedback Resistor
The plots of inverting and non-inverting frequency response,
see Figure 1 and Figure 2 in the typical performance section,
illustrate the performance of the HA5023 in various closed
loop gain configurations. Although the bandwidth depen-
dency 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 R
F
. All current
feedback amplifiers require a feedback resistor, even for
unity gain applications, and R
F
, in conjunction with the inter-
nal compensation capacitor, sets the dominant pole of the
frequency response. Thus, the amplifier's bandwidth is
inversely proportional to R
F
. The HA5023 design is opti-
mized for a 1000
R
F
at a gain of +1. Decreasing R
F
in a
unity gain application decreases stability, resulting in exces-
sive peaking and overshoot. At higher gains the amplifier is
more stable, so R
F
can be decreased in a trade-off of stabil-
ity for bandwidth.
The table below lists recommended R
F
values for various
gains, and the expected bandwidth.
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. If leaded
components are used the leads must be kept short espe-
cially for the power supply decoupling components and
those components connected to the inverting input.
Attention must be given to decoupling the power supplies. A
large value (10
F) tantalum or electrolytic capacitor in paral-
lel with a small value (0.1
F) chip capacitor works well in
most cases.
A ground plane is strongly recommended to control noise.
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. It is recom-
mended that the ground plane be removed under traces
connected to -IN, and that connections to -IN be kept as
short as possible to minimize the capacitance from this node
to ground.
Driving Capacitive Loads
Capacitive loads will degrade the amplifier's phase margin
resulting in frequency response peaking and possible oscilla-
tions. In most cases the oscillation can be avoided by placing
an isolation resistor (R) in series with the output as shown in
Figure 34.
FIGURE 34. PLACEMENT OF THE OUTPUT ISOLATION
RESISTOR, R
The selection criteria for the isolation resistor is highly
dependent on the load, but 27
has been determined to be
a good starting value.
Power Dissipation Considerations
Due to the high supply current inherent in dual amplifiers, care
must be taken to insure that the maximum junction tempera-
ture (T
J
,
see Absolute Maximum Ratings) is not exceeded.
Figure 35 shows the maximum ambient temperature versus
supply voltage for the available package styles. It is recom-
mended that thermal calculations, which take into account
output power, be performed by the designer.

NOTES:
1. Absolute maximum ratings are limiting values, applied individually, beyond which the serviceability of the circuit may be impaired. Func-
tional operation under any of these conditions is not necessarily implied.
2. Output is protected for short circuits to ground. Brief short circuits to ground will not degrade reliability, however, continuous (100% duty
cycle) output current should not exceed 15mA for maximum reliability.
