The EL2170C/EL2270C/EL2470C are single/dual/quad current-feedback operational amplifiers which achieve a b 3 dB
bandwidth of 70 MHz at a gain of a 1 while consuming only
1 mA of supply current per amplifier. They will operate with
dual supplies ranging from g 1.5V to g 6V, or from single supplies ranging from a 3V to a 12V. In spite of their low supply
current, the EL2270C and the EL2470C can output 55 mA while
swinging to g 4V on g 5V supplies. The EL2170C can output
100 mA with similar output swings. These attributes make the
EL2170C/EL2270C/EL2470C excellent choices for low power
and/or low voltage cable-driver, HDSL, or RGB applications.

For applications where board space is extremely critical, the
EL2170C is available in the tiny 5-Lead SOT23 package, which
has a footprint 28% the size of an 8-Lead SOIC. The EL2170C/
EL2270C/EL2470C are each also available in industry standard
pinouts in PDIP and SOIC packages.
For Single and Dual applications with disable, consider the
EL2176C (8-Pin Single) or EL2276C (14-Pin Dual). For higher
speed applications where power is still a concern, consider the
EL2180C/El2186C family which also comes in similar Single,
Dual, Triple and Quad configurations. The EL2180C/EL2186C
family provides a b 3 dB bandwidth of 250 MHz while consuming 3 mA of supply current per amplifier.

Applications Information
Power Supply Bypassing and Printed
Circuit Board Layout
Product Description
As with any high-frequency device, good printed
circuit board layout is necessary for optimum
performance. Ground plane construction is highly recommended. 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 4.7 mF tantalum capacitor in
parallel with a 0.1 mF capacitor has been shown
to work well when placed at each supply pin.
The EL2170C/EL2270C/EL2470C are currentfeedback operational amplifiers that offer a wide
b 3 dB bandwidth of 70 MHz and a low supply
current of 1 mA per amplifier. All of these products also feature high output current drive. The
EL2170C can output 100 mA, while the EL2270C
and the EL2470C can output 55 mA per amplifier. The EL2170C/EL2270C/EL2470C work with
supply voltages ranging from a single 3V to
g 6V, and they are also capable of swinging to
within 1V of either supply on the input and the
output. Because of their current-feedback topology, the EL2170C/EL2270C/EL2470C do not
have the normal gain-bandwidth product associated with voltage-feedback operational amplifiers. This allows their b 3 dB 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 EL2170C/EL2270C/EL2470C the ideal
choice for many low-power/high-bandwidth applications such as portable computing, HDSL,
and video processing.
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). Ground plane construction should be used, but 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 their additional series
inductance. Use of sockets, particularly for the
SO package should be avoided if possible. Sockets add parasitic inductance and capacitance
which will result in some additional peaking and
overshoot.
For applications where board space is extremely
critical, the EL2170C is available in the tiny 5Lead SOT23 package, which has a footprint 28%
the size of an 8-Lead SOIC. The EL2170C/
EL2270C/EL2470C are each also available in industry standard pinouts in PDIP and SOIC packages.
Capacitance at the Inverting Input
Any manufacturer’s high-speed voltage- or current-feedback 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
open-loop response. The use of large value feedback and gain resistors further exacerbates the
problem by further lowering the pole frequency.
For Single and Dual applications with disable,
consider the EL2176C (8-Pin Single) and
EL2276C (14-Pin Dual). If higher speed is required, refer to the EL2180C/EL2186C family
which provides Singles, Duals, Triples, and
Quads with 250 MHz of bandwidth while consuming 3 mA of supply current per amplifier.

Supply Voltage Range and SingleSupply Operation
Applications Information Ð Contd.
The experienced user with a large amount of PC
board layout experience may find in rare cases
that the EL2170C/EL2270C/EL2470C have less
bandwidth than expected. The reduction of feedback resistor values (or the addition of a very
small amount of external capacitance at the inverting input, e. g. 0.5 pF) will increase bandwidth as desired. Please see the curves for Frequency Response for Various RF and RG, and
Frequency Response for Various CIN b .
The EL2170C/EL2270C/EL2470C have been designed to operate with supply voltages having a
span of greater than 3V, and less than 12V. In
practical terms, this means that the EL2170C/
EL2270C/EL2470C will operate on dual supplies
ranging from g 1.5V to g 6V. With a single-supply, the EL2170C/EL2270C/EL2470C will operate from a 3V to a 12V.
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 EL2170C/EL2270C/
EL2470C have an input voltage range that extends to within 1V of either supply. So, for example, on a single a 5V supply, the EL2170C/
EL2270C/EL2470C have an input range which
spans from 1V to 4V. The output range of the
EL2170C/EL2270C/EL2470C is also quite large,
extending to within 1V of the supply rail. On a
g 5V supply, the output is therefore capable of
swinging from b 4V to a 4V. Single-supply output range is even larger because of the increased
negative swing due to the external pull-down resistor to ground. On a single a 5V supply, output
voltage range is about 0.3V to 4V.
Feedback Resistor Values
The EL2170C/EL2270C/EL2470C have been designed and specified at gains of a 1 and a 2 with
RF e 1 kX. This value of feedback resistor gives
70 MHz of b 3 dB bandwidth at AV e a 1 with
about 1.5 dB of peaking, and 60 MHz of b 3 dB
bandwidth at AV e a 2 with about 0.5 dB of
peaking. Since the EL2170C/EL2270C/EL2470C
are current-feedback amplifiers, 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.
Because the EL2170C/EL2270C/EL2470C are
current-feedback amplifiers, their gain-bandwidth product is not a constant for different
closed-loop gains. This feature actually allows
the EL2170C/EL2270C/EL2470C to maintain
about the same b 3 dB bandwidth, regardless of
closed-loop gain. However, as closed-loop gain is
increased, bandwidth decreases slightly while stability increases. Since the loop stability is improving with higher closed-loop gains, it becomes
possible to reduce the value of RF below the specified 1 kX and still retain stability, resulting in
only a slight loss of bandwidth with increased
closed-loop gain.
Video Performance
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 150X, because of the change in output current with DC
level. Until the EL2170C/EL2270C/EL2470C,
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 more than
the entire 1 mA supply current of each EL2170C/
EL2270C/EL2470C amplifier! Special circuitry
has been incorporated in the EL2170C/
EL2270C/EL2470C to reduce the variation of
output impedance with current output. This results in dG and dP specifications of 0.15% and
0.15§ while driving 150X at a gain of a 2.

Current Limiting
Video Performance has also been measured with
a 500X load at a gain of a 1. Under these conditions, the EL2170C/EL2270C/EL2470C have dG
and dP specifications of 0.01% and 0.02§ respectively while driving 500 X at AV e a 1.
The EL2170C/EL2270C/EL2470C have no internal current-limiting circuitry. If any output is
shorted, it is possible to exceed the Absolute
Maximum Ratings for output current or power
dissipation, potentially resulting in the destruction of the device.
Output Drive Capability
Power Dissipation
In spite of its low 1 mA of supply current, the
EL2170C is capable of providing a minimum of
g 80 mA of output current. Similarly, each amplifier of the EL2270C and the EL2470C is capable of providing a minimum of g 50 mA. These
output drive levels are unprecedented in amplifiers running at these supply currents. With a minimum g 80 mA of output drive, the EL2170C is
capable of driving 50X loads to g 4V, making it
an excellent choice for driving isolation transformers in telecommunications applications.
Similarly, the g 50 mA minimum output drive of
each EL2270C and EL2470C amplifier allows
swings of g 2.5V into 50X loads.
With the high output drive capability of the
EL2170C/EL2270C/EL2470C, it is possible to
exceed the 150§ C Absolute Maximum junction
temperature under certain very high load current
conditions. Generally speaking, when RL falls below about 25X, 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 EL2170C/EL2270C/EL2470C to
remain in the safe operating area. These parameters are calculated as follows:

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 EL2170C/
EL2270C/EL2470C 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 5X and
50X) 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.
