Applications Information
Product Description
particularly for the SO package, should be avoided if
possible. Sockets add parasitic inductance and capacitance which will result in additional peaking and
overshoot.
The EL5392C is a current-feedback operational amplifier that offers a wide -3dB bandwidth of 600MHz and a
low supply current of 6mA per amplifier. The EL5392C
works with supply voltages ranging from a single 5V to
10V and they are also capable of swinging to within 1V
of either supply on the output. Because of their currentfeedback topology, the EL5392C does not have the normal gain-bandwidth product associated with voltagefeedback operational amplifiers. Instead, its -3dB bandwidth to remain relatively constant as closed-loop gain is
increased. This combination of high bandwidth and low
power, together with aggressive pricing make the
EL5392C the ideal choice for many low-power/highbandwidth applications such as portable, handheld, or
battery-powered equipment.
Capacitance at the Inverting Input
Any manufacturer’s high-speed voltage- or currentfeedback amplifier can be affected by stray capacitance
at the inverting input. For inverting gains, this parasitic
capacitance has little effect because the inverting input is
a virtual ground, but for non-inverting gains, this capacitance (in conjunction with the feedback and gain
resistors) creates a pole in the feedback path of the
amplifier. This pole, if low enough in frequency, has the
same destabilizing effect as a zero in the forward openloop response. The use of large-value feedback and gain
resistors exacerbates the problem by further lowering
the pole frequency (increasing the possibility of
oscillation.)
For varying bandwidth needs, consider the EL5191C
with 1GHz on a 9mA supply current or the EL5193C
with 300MHz on a 4mA supply current. Versions
include single, dual, and triple amp packages with 5-pin
SOT23, 16-pin QSOP, and 8-pin or 16-pin SO outlines.
The EL5392C has been optimized with a 375Ω feedback
resistor. With the high bandwidth of these amplifiers,
these resistor values might cause stability problems
when combined with parasitic capacitance, thus ground
plane is not recommended around the inverting input pin
of the amplifier.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, good printed circuit
board layout is necessary for optimum performance.
Low impedance ground plane construction is essential.
Surface mount components are recommended, but if
leaded components are used, lead lengths should be as
short as possible. The power supply pins must be well
bypassed to reduce the risk of oscillation. The combination of a 4.7µF tantalum capacitor in parallel with a
0.01µF capacitor has been shown to work well when
placed at each supply pin.
Feedback Resistor Values
The EL5392C has been designed and specified at a gain
of +2 with RF approximately 375Ω. This value of feedback resistor gives 300MHz of -3dB bandwidth at AV=2
with 2dB of peaking. With AV=-2, an RF of 375Ω gives
275MHz of bandwidth with 1dB of peaking. Since the
EL5392C is a current-feedback amplifier, it is also possible to change the value of RF to get more bandwidth.
As seen in the curve of Frequency Response for Various
RF and RG, bandwidth and peaking can be easily modified by varying the value of the feedback resistor.
For good AC performance, parasitic capacitance should
be kept to a minimum, especially at the inverting input.
(See the Capacitance at the Inverting Input section) Even
when ground plane construction is used, it should be
removed from the area near the inverting input to minimize any stray capacitance at that node. Carbon or
Metal-Film resistors are acceptable with the Metal-Film
resistors giving slightly less peaking and bandwidth
because of additional series inductance. Use of sockets,
Because the EL5392C is a current-feedback amplifier,
its gain-bandwidth product is not a constant for different
closed-loop gains. This feature actually allows the
EL5392C to maintain about the same -3dB bandwidth.
As gain is increased, bandwidth decreases slightly while
stability increases. Since the loop stability is improving
12
with higher closed-loop gains, it becomes possible to
reduce the value of RF below the specified 375Ω and
still retain stability, resulting in only a slight loss of
bandwidth with increased closed-loop gain.
EL5392C has dG and dP specifications of 0.03% and
0.05°, respectively.
Output Drive Capability
In spite of its low 6mA of supply current, the EL5392C
is capable of providing a minimum of ±95mA of output
current. With a minimum of ±95mA of output drive, the
EL5392C is capable of driving 50Ω loads to both rails,
making it an excellent choice for driving isolation transformers in telecommunications applications.
Supply Voltage Range and Single-Supply
Operation
The EL5392C has been designed to operate with supply
voltages having a span of greater than 5V and less than
10V. In practical terms, this means that the EL5392C
will operate on dual supplies ranging from ±2.5V to
±5V. With single-supply, the EL5392C will operate
from 5V to 10V.
Driving Cables and Capacitive Loads
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 EL5392C from the cable and allow
extensive capacitive drive. However, other applications
may have high capacitive loads without a back-termination resistor. In these applications, a small series resistor
(usually between 5Ω and 50Ω) can be placed in series
with the output to eliminate most peaking. The gain
resistor (RG) can then be chosen to make up for any gain
loss which may be created by this additional resistor at
the output. In many cases it is also possible to simply
increase the value of the feedback resistor (RF) to reduce
the peaking.
As supply voltages continue to decrease, it becomes necessary to provide input and output voltage ranges that
can get as close as possible to the supply voltages. The
EL5392C has an input range which extends to within 2V
of either supply. So, for example, on ±5V supplies, the
EL5392C has an input range which spans ±3V. The output range of the EL5392C is also quite large, extending
to within 1V of the supply rail. On a ±5V supply, the
output is therefore capable of swinging from -----4V to
+4V. Single-supply output range is larger because of the
increased negative swing due to the external pull-down
resistor to ground.
Video Performance
Current Limiting
For good video performance, an amplifier is required to
maintain the same output impedance and the same frequency response as DC levels are changed at the output.
This is especially difficult when driving a standard video
load of 150Ω, because of the change in output current
with DC level. Previously, good differential gain could
only be achieved by running high idle currents through
the output transistors (to reduce variations in output
impedance.) These currents were typically comparable
to the entire 6mA supply current of each EL5392C
amplifier. Special circuitry has been incorporated in the
EL5392C to reduce the variation of output impedance
with current output. This results in dG and dP specifications of 0.015% and 0.04°, while driving 150Ω at a gain
of 2.
The EL5392C has no internal current-limiting circuitry.
If the output is shorted, it is possible to exceed the Absolute Maximum Rating for output current or power
dissipation, potentially resulting in the destruction of the
device.
Power Dissipation
With the high output drive capability of the EL5392C, it
is possible to exceed the 125°C Absolute Maximum
junction temperature under certain very high load current conditions. Generally speaking when RL falls below
about 25Ω, it is important to calculate the maximum
junction temperature (TJMAX ) for the application to
determine if power supply voltages, load conditions, or
package type need to be modified for the EL5392C to
Video performance has also been measured with a 500Ω
load at a gain of +1. Under these conditions, the
