100MHz Current Feedback
Video Amplifier With Disable
FN2845.9
Features
• Wide Unity Gain Bandwidth . . . . . . . . . . . . . . . . . 100MHz
The HA-5020 is a wide bandwidth, high slew rate amplifier
optimized for video applications and gains between 1 and
10. Manufactured on Intersil’s Reduced Feature
Complementary Bipolar DI process, this amplifier uses
current mode feedback to maintain higher bandwidth at a
given gain than conventional voltage feedback amplifiers.
Since it is a closed loop device, the HA-5020 offers better
gain accuracy and lower distortion than open loop buffers.
The HA-5020 features low differential gain and phase and
will drive two double terminated 75Ω coax cables to video
levels with low distortion. Adding a gain flatness
performance of 0.1dB makes this amplifier ideal for
demanding video applications. The bandwidth and slew rate
of the HA-5020 are relatively independent of closed loop
gain. The 100MHz unity gain bandwidth only decreases to
60MHz at a gain of 10. The HA-5020 used in place of a
conventional op amp will yield a significant improvement in
the speed power product. To further reduce power, HA-5020
has a disable function which significantly reduces supply
current, while forcing the output to a true high impedance
state. This allows the outputs of multiple amplifiers to be
wire-OR’d into multiplexer configurations. The device also
includes output short circuit protection and output offset
voltage adjustment.
For multi channel versions of the HA-5020 see the HA5022
dual with disable, HA5023 dual, HA5013 triple and HA5024
quad with disable op amp data sheets.

NOTES:
2. Suggested VOS Adjust Circuit: The inverting input current (-IBIAS) can be adjusted with an external 10kΩ pot between pins 1 and 5, wiper
connected to V+. Since -IBIAS flows through the feedback resistor (RF), the result is an adjustment in offset voltage. The amount of offset voltage
adjustment is determined by the value of RF (∆VOS = ∆-IBIAS*RF).
3. RL = 100Ω, VIN = 10V. This is the minimum current which must be pulled out of the Disable pin in order to disable the output. The output is
considered disabled when -10mV ≤ VOUT ≤ +10mV.
4. VIN = 0V. This is the maximum current that can be pulled out of the Disable pin with the HA-5020 remaining enabled. The HA-5020 is considered
disabled when the supply current has decreased by at least 0.5mA.
5. VOUT switches from -10V to +10V, or from +10V to -10V. Specification is from the 25% to 75% points.

RL = 100Ω, VOUT = 1V. Measured from 10% to 90% points for rise/fall times; from 50% points of input and output for propagation delay.
This parameter is not tested. The limits are guaranteed based on lab characterization, and reflect lot-to-lot variation.
VIN = +10V, Disable = +15V to 0V. Measured from the 50% point of Disable to VOUT = 0V.
VIN = +10V, Disable = 0V to +15V. Measured from the 50% point of Disable to VOUT = 10V.
VIN = 0V, Force VOUT from 0V to ±10V, tR = tF = 50ns.
Measured with a VM700A video tester using a NTC-7 composite VITS.
See “Typical Performance Curves” for more information.
VCM = ±2.5V. At -40oC product is tested at VCM = ±2.25V because short test duration does not allow self heating.
RL = 100Ω. VIN = 2.5V. This is the minimum current which must be pulled out of the Disable pin in order to disable the output. The output is
considered disabled when -10mV ≤ VOUT ≤ +10mV.
16. VOUT switches from -2V to +2V, or from +2V to -2V. Specification is from the 25% to 75% points.

HA-5020
Application Information
Driving Capacitive Loads
Optimum Feedback Resistor
The plots of inverting and non-inverting frequency response
illustrate the performance of the HA-5020 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 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 HA-5020 design is optimized
for a 1000Ω RF at a gain of +1. Decreasing RF in a unity gain
application decreases stability, resulting in excessive peaking
and overshoot. At higher gains the amplifier is more stable, so
RF can be decreased in a trade-off of stability for bandwidth.
The table below lists recommended RF 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 (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 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.

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.

FIGURE 6. PLACEMENT OF THE OUTPUT ISOLATION
RESISTOR, R
The selection criteria for the isolation resistor is highly
dependent on the load, but 27Ω has been determined to be
a good starting value.
Enable/Disable Function
When enabled the amplifier functions as a normal current
feedback amplifier with all of the data in the electrical
specifications table being valid and applicable. When
disabled the amplifier output assumes a true high
impedance state and the supply current is reduced
significantly.
The circuit shown in Figure 7 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.

FIGURE 7. SIMPLIFIED SCHEMATIC OF ENABLE/DISABLE
FUNCTION
When VCC 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 D1 will not
turn on, and the TTL gate will sink enough current to keep
point “A” at its proper voltage. When VCC is greater than +5V
the DISABLE pin should be driven with an open collector
device that has a breakdown rating greater than VCC .
HA-5020
Referring to Figure 7, it can be seen that R6 will act as a pull-up
resistor to +VCC 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 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.
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 HA-5020, eliminates the
multiplexer problems because the external mux chip is not
needed, and the HA-5020 can drive low impedance (large
capacitance) loads if a series isolation resistor is used.
Typical Applications
Referring to Figure 9, 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
amplifiers, U2, are configured in a gain of +2 to set the circuit
gain equal to one. Resistors R2 and R3 determine the
amplifier gain, and if a different gain is desired R2 should be
changed according to the equation G = (1 + R3/R2). R3 sets
the frequency response of the amplifier so you should refer
to the manufacturers data sheet before changing its value.
R5, C1 and D1 are an asymmetrical charge/discharge time
circuit which configures U1 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. R4 is enclosed
in the feedback loop of the amplifier so that the large open
loop amplifier gain of U2 will present the load with a small
closed loop output impedance while keeping the amplifier
stable for all values of load capacitance.
Two Channel Video Multiplexer
Referring to the amplifier U1A in Figure 8, R1 terminates the
cable in its characteristic impedance of 75Ω, and R4 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 R3 can be changed if a different network
gain is desired. R5 holds the disable pin at ground thus
inhibiting the amplifier until the switch, S1, 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, U1B, 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
HA-5020 is often used as a remote video multiplexer, and the
multiplexer may be extended by adding more amplifier ICs.
The circuit shown in Figure 9 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
and independent of any multiplexing action; thus, problem
two has been solved. The multiplexer transition time is
approximately 15µs with the component values shown.
