Dual, 125MHz, Video Current Feedback
Amplifier with Disable
Features
• Dual Version of HA-5020
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.

• Guaranteed Specifications at ±5V Supplies
The low differential gain and phase, 0.1dB gain flatness, and
ability to drive two back terminated 75Ω 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.
Applications
The current feedback design allows the user to take
• Video Multiplexers; Video Switching and Routing
• Video Gain Block
advantage of the amplifier’s bandwidth dependency on the
feedback resistor. By reducing R , the bandwidth can be

increased to compensate for decreases at higher closed
loop gains or heavy output loads.

NOTES:

1. Maximum power dissipation, including output load, must be designed to maintain junction temperature below 175 C for die, and below 150 C
for plastic packages. See Application Information section for safe operating area information.
2. θ is measured with the component mounted on an evaluation PC board in free air.
JA
3. The non-inverting input of unused amplifiers must be connected to GND.
4. 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.

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
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.

Decreasing R in a unity gain application decreases stability,

resulting in excessive peaking and overshoot. At higher
gains the amplifier is more stable, so R can be decreased
in a trade-off of stability for bandwidth.
The selection criteria for the isolation resistor is highly
dependent on the load, but 27Ω has been determined to be
a good starting value.

The table below lists recommended R values for various

PC Board Layout
140
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 (10µF) tantalum or electrolytic capacitor in
parallel with a small value (0.1µF) 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

larger this capacitance, the worse the gain peaking, resulting
in pulse overshoot and possible instability. It is

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
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 350µA 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.
performance. The other circuit, U , 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.

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.

When V

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 will not
turn on, and the TTL gate will sink enough current to keep
Referring to Figure 10, both inputs are terminated in their
characteristic impedance; 75Ω is typical for video
applications. Since the drivers usually are terminated in their
characteristic impedance the input gain is 0.5, thus the

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 20µA 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.

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
