Applications Information
Product Description
The 5962-0721201QXC is a dual current feedback
operational amplifier designed for video distribution solutions.
It is a dual current mode feedback amplifier with low distortion
while drawing moderately low supply current. It is built using
Intersil’s proprietary complimentary bipolar process. Due to
the current feedback architecture, the 5962-0721201QXC
closed-loop 3dB bandwidth is dependent on the value of the
feedback resistor. First the desired bandwidth is selected by
choosing the feedback resistor, RF, and then the gain is set by
picking the gain resistor, RG. The curves at the beginning of
the Typical Performance Curves section show the effect of
varying both RF and RG. The 3dB bandwidth is somewhat
dependent on the power supply voltage.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, good printed circuit
board layout is necessary for optimum performance. Ground
8
plane construction is highly recommended. Lead lengths
should be as short as possible, below ¼”. The power supply
pins must be well bypassed to reduce the risk of oscillation.
A 4.7µF tantalum capacitor in parallel with a 0.1µF ceramic
capacitor is adequate for each supply pin.
For good AC performance, parasitic capacitances should be
kept to a minimum, especially at the inverting input. This implies
keeping the ground plane away from this pin. Carbon resistors
are acceptable, while use of wire-wound resistors should not be
used because of their parasitic inductance. Similarly, capacitors
should be low inductance for best performance.
Capacitance at the Inverting Input
Due to the topology of the current feedback amplifier, stray
capacitance at the inverting input will affect the AC and
transient performance of the 5962-0721201QXC when
operating in the non-inverting configuration.
In the inverting gain mode, added capacitance at the inverting
input has little effect since this point is at a virtual ground and
stray capacitance is therefore not “seen” by the amplifier.

Feedback Resistor Values
Single Supply Operation
The 5962-0721201QXC has been designed and specified
with RF = 500Ω for AV = +2. This value of feedback resistor
yields extremely flat frequency response with little to no
peaking out to 200MHz. As is the case with all current
feedback amplifiers, wider bandwidth, at the expense of
slight peaking, can be obtained by reducing the value of the
feedback resistor. Inversely, larger values of feedback
resistor will cause rolloff to occur at a lower frequency. See
the curves in the Typical Performance Curves section which
show 3dB bandwidth and peaking vs. frequency for various
feedback resistors and various supply voltages.
If a single supply is desired, values from +5V to +12V can be
used as long as the input common mode range is not
exceeded. When using a single supply, be sure to either 1)
DC bias the inputs at an appropriate common mode voltage
and AC couple the signal, or 2) ensure the driving signal is
within the common mode range of the 5962-0721201QXC.
Driving Cables and Capacitive Loads
The 5962-0721201QXC was designed with driving multiple
coaxial cables in mind. With 450mA of output drive and low
output impedance, driving six, 75Ω double terminated
coaxial cables to ±11V with one 5962-0721201QXC is
practical.
Bandwidth vs Temperature
Whereas many amplifier's supply current and consequently
3dB bandwidth drop off at high temperature, the 59620721201QXC was designed to have little supply current
variations with temperature. An immediate benefit from this
is that the 3dB bandwidth does not drop off drastically with
temperature.
When used as a cable driver, double termination is always
recommended for reflection-free performance. For those
applications, the back termination series resistor will
decouple the 5962-0721201QXC from the capacitive cable
and allow extensive capacitive drive.
Other applications may have high capacitive loads without
termination resistors. In these applications, an additional
small value (5Ω to 50Ω) resistor in series with the output will
eliminate most peaking.
Supply Voltage Range
The 5962-0721201QXC has been designed to operate with
supply voltages from ±2.5V to ±6V. Optimum bandwidth,
slew rate, and video characteristics are obtained at higher
supply voltages. However, at ±2.5V supplies, the 3dB
bandwidth at AV = +5 is a respectable 200MHz.
The schematic below shows the EL8108 driving 6 double
terminated cables, each of average length of 50 feet.

NOTES:
1. Index area: A notch or a pin one identification mark shall be located 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. Alternately, a tab (dimension k)
may be used to identify pin one.
2. If a pin one identification mark is used in addition to a tab, the limits of dimension k do not apply.
3. This dimension allows for off-center lid, meniscus, and glass
overrun.
4. Dimensions b1 and c1 apply to lead base metal only. Dimension
M applies to lead plating and finish thickness. 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.
5. N is the maximum number of terminal positions.
6. Measure dimension S1 at all four corners.
7. For bottom-brazed lead packages, no organic or polymeric materials shall be molded to the bottom of the package to cover the
leads.
8. Dimension Q shall be measured at the point of exit (beyond the
meniscus) of the lead from the body. Dimension Q minimum
shall be reduced by 0.0015 inch (0.038mm) maximum when solder dip lead finish is applied.
9. Dimensioning and tolerancing per ANSI Y14.5M - 1982.
10. Controlling dimension: INCH.
