HA5025
Quad, 125MHz Video
Current Feedback Amplifier
The HA5025 is a wide bandwidth high slew rate quad
amplifier optimized for video applications and gains between
1 and 10. It is a current feedback amplifier and thus yields
less bandwidth degradation 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
advantage of the amplifier's bandwidth dependency on the
feedback resistor.
The performance of the HA5025 is very similar to the
popular Intersil HA-5020.

Application Information
Optimum Feedback Resistor
The plots of inverting and non-inverting frequency response,
see Figure 8 and Figure 9 in the typical performance section,
illustrate the performance of the HA5025 in various closed
loop gain configurations. Although the 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 R
F
. All current feedback
amplifiers require a feedback resistor, even for unity gain
applications, and R
F
, in conjunction with the internal
compensation capacitor, sets the dominant pole of the
frequency response. Thus, the amplifier's bandwidth is
inversely proportional to R
F
. The HA5025 design is optimized
for a 1000
R
F
at a gain of +1. Decreasing R
F
in a unity gain
application decreases stability, resulting in excessive peaking
and overshoot. At higher gains the amplifier is more stable, so
R
F
can be decreased in a trade-off of stability for bandwidth.
The following table 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
especially 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
parallel 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 recommended
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
oscillations. In most cases the oscillation can be avoided by
placing an isolation resistor (R) in series with the output as
shown in Figure 6.
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 quad amplifiers,
care must be taken to insure that the maximum junction
temperature (T
J
, see Absolute Maximum Ratings) is not
exceeded. Figure 7 shows the maximum ambient temperature
versus supply voltage for the available package styles (PDIP,
SOIC). At V
S
=
5V quiescent operation both package styles
may be operated over the full industrial range of -40
o
C to
85
o
C. It is recommended that thermal calculations, which take
into account output power, be performed by the designer.
