HA5022
Dual, 125MHz, Video Current Feedback
Amplifier with Disable
The HA5022 is a dual version of the popular Intersil HA5020.
It features wide bandwidth and high slew rate, and is
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 HA5022 also features a disable function that
significantly reduces supply current while forcing the output
to a true high impedance state. This functionality allows 2:1
video multiplexers to be implemented with a single IC.
The current feedback design allows the user to take
advantage of the amplifier's bandwidth dependency on the
feedback resistor. By reducing R
F
, the bandwidth can be
increased to compensate for decreases at higher closed
loop gains or heavy output loads.

Application Information
Optimum Feedback Resistor
The plots of inverting and non-inverting frequency response,
see Figure 11 and Figure 12 in the Typical Performance
Curves section, illustrate the performance of the HA5022 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
HA5022 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 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
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 dual 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.

disabled the amplifier output assumes a true high
impedance state and the supply current is reduced
significantly.
The circuit shown in Figure 8 is a simplified schematic of the
enable/disable function. The large value resistors in series
with the DISABLE pin makes it appear as a current source to
the driver. When the driver pulls this pin low current flows out
of the pin and into the driver. This current, which may be as
large as 350
A when external circuit and process variables
are at their extremes, is required to insure that point "A"
achieves the proper potential to disable the output. The
driver must have the compliance and capability of sinking all
of this current.
When V
CC
is +5V the DISABLE pin may be driven with a
dedicated TTL gate. The maximum low level output voltage
of the TTL gate, 0.4V, has enough compliance to insure that
the amplifier will always be disabled even though D
1
will not
turn on, and the TTL gate will sink enough current to keep
point "A" at its proper voltage. When V
CC
is greater than +5V
the DISABLE pin should be driven with an open collector
device that has a breakdown rating greater than V
CC
.
Referring to Figure 8, it can be seen that R
6
will act as a pull-
up resistor to +V
CC
if the DISABLE pin is left open. In those
cases where the enable/disable function is not required on
all circuits some circuits can be permanently enabled by
letting the DISABLE pin float. If a driver is used to set the
enable/disable level, be sure that the driver does not sink
more than 20
A when the DISABLE pin is at a high level.
TTL gates, especially CMOS versions, do not violate this
criteria so it is permissible to control the enable/disable
function with TTL.
Typical Applications
Two Channel Video Multiplexer
Referring to the amplifier U
1A
in Figure 9, R
1
terminates the
cable in its characteristic impedance of 75
, and R
4
back
terminates the cable in its characteristic impedance. The
amplifier is set up in a gain configuration of +2 to yield an
overall network gain of +1 when driving a double terminated
cable. The value of R
3
can be changed if a different network
gain is desired. R
5
holds the disable pin at ground thus
inhibiting the amplifier until the switch, S
1
, is thrown to
position 1. At position 1 the switch pulls the disable pin up to
the plus supply rail thereby enabling the amplifier. Since all
of the actual signal switching takes place within the amplifier,
it's differential gain and phase parameters, which are 0.03%
and 0.03 degrees respectively, determine the circuit's
performance. The other circuit, U
1B
, operates in a similar
manner.
When the plus supply rail is 5V the disable pin can be driven
by a dedicated TTL gate as discussed earlier. If a multiplexer
IC or its equivalent is used to select channels its logic must
be break before make. When these conditions are satisfied
the HA5022 is often used as a remote video multiplexer, and
the multiplexer may be extended by adding more amplifier
ICs.
Low Impedance Multiplexer
Two common problems surface when you try to multiplex
multiple high speed signals into a low impedance source
such as an A/D converter. The first problem is the low source
impedance which tends to make amplifiers oscillate and
causes gain errors. The second problem is the multiplexer
which supplies no gain, introduces all kinds of distortion and
limits the frequency response. Using op amps which have an
enable/disable function, such as the HA5022, eliminates the
multiplexer problems because the external mux chip is not
needed, and the HA5022 can drive low impedance (large
capacitance) loads if a series isolation resistor is used.
Referring to Figure 10, both inputs are terminated in their
characteristic impedance; 75
is typical for video
applications. Since the drivers usually are terminated in their
characteristic impedance the input gain is 0.5, thus the
amplifiers, U
2
, are configured in a gain of +2 to set the circuit
gain equal to one. Resistors R
2
and R
3
determine the
amplifier gain, and if a different gain is desired R
2
should be
changed according to the equation G = (1 + R
3
/R
2
). R
3
sets
the frequency response of the amplifier so you should refer
to the manufacturers data sheet before changing its value.
R
5
, C
1
and D
1
are an asymmetrical charge/discharge time
circuit which configures U
1
as a break before make switch to
prevent both amplifiers from being active simultaneously. If
this design is extended to more channels the drive logic
must be designed to be break before make. R
4
is enclosed
in the feedback loop of the amplifier so that the large open
loop amplifier gain of U
2
will present the load with a small
closed loop output impedance while keeping the amplifier
stable for all values of load capacitance.
The circuit shown in Figure 10 was tested for the full range of
capacitor values with no oscillations being observed; thus,
problem one has been solved.The frequency and gain
characteristics of the circuit are now those of the amplifier
independent of any multiplexing action; thus, problem two
has been solved. The multiplexer transition time is
approximately 15
s with the component values shown.
