PRODUCT DESCRIPTION
than the competition while offering higher output drive. Impor-
tant specs like voltage noise and offset voltage are less than half
of those for the EL2020.
The ADEL2020 is an improved second source to the EL2020.
This op amp improves on all the key dynamic specifications
while offering lower power and lower cost. The ADEL2020 of-
fers 50% more bandwidth and gain flatness of 0.1 dB to beyond
25 MHz. In addition, differential gain and phase are less than
0.05% and 0.05° while driving one back terminated cable (150Ω).
The ADEL2020 also features an improved disable feature. The
disable time (to high output impedance) is 100 ns with guaran-
teed break before make. Finally the ADEL2020 is offered in the
industrial temperature range of –40°C to +85°C in both plastic
DIP and SOIC package.
The ADEL2020 offers other significant improvements. The
most important of these is lower power supply current, 33% less

The maximum power that can be safely dissipated by the
ADEL2020 is limited by the associated rise in junction tem-
perature. For the plastic packages, the maximum safe junction
temperature is 145°C. If the maximum is exceeded momen-
tarily, proper circuit operation will be restored as soon as the
die temperature is reduced. Leaving the device in the “over-
heated” condition for an extended period can result in device
burnout. To ensure proper operation, it is important to observe
the derating curves below.
While the ADEL2020 is internally short circuit protected, this
may not be sufficient to guarantee that the maximum junction
temperature is not exceeded under all conditions.
NOTES
1Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the
operational section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

ESD SUSCEPTIBILITY
ESD (electrostatic discharge) sensitive device. Electrostatic
charges as high as 4000 volts, which readily accumulate on the
human body and on test equipment, can discharge without
detection. Although the ADEL2020 features ESD protection
circuitry, permanent damage may still occur on these devices if
they are subjected to high energy electrostatic discharges.
Therefore, proper ESD precautions are recommended to avoid
any performance degradation or loss of functionality.

ADEL2020
GENERAL DESIGN CONSIDERATIONS
In cases where the amplifier is driving a high impedance load,
the input to output isolation will decrease significantly if the in-
put signal is greater than about 1.2 V peak to peak. The isola-
tion can be restored to the 50 dB level by adding a dummy load
(say 150 Ω) at the amplifier output. This will attenuate the
feedthrough signal. (This is not an issue for multiplexer applica-
tions where the outputs of multiple ADEL2020s are tied to-
gether as long as at least one channel is in the ON state.) The
input impedance of the disable pin is about 35 kΩ in parallel
with a few pF. When grounded, about 50 µA flows out of the
disable pin for ±5 V supplies.
The ADEL2020 is a current feedback amplifier optimized for
use in high performance video and data acquisition systems.
Since it uses a current feedback architecture, its closed-loop
bandwidth depends on the value of the feedback resistor. The
–3 dB bandwidth is also somewhat dependent on the power
supply voltage. Lowering the supplies increases the values of in-
ternal capacitances, reducing the bandwidth. To compensate for
this, smaller values of feedback resistor are used at lower supply
voltages.
POWER SUPPLY BYPASSING
Break before make operation is guaranteed by design. If driven
by standard CMOS logic, the disable time (until the output is
high impedance), is about 100 ns and the enable time (to low
impedance output) is about 160 ns. Since it has an internal pull-
up resistor of about 35 kΩ, the ADEL2020 can be used with
open drain logic as well. In this case, the enable time is in-
creased to about 1 µs.
Adequate power supply bypassing can be critical when optimiz-
ing the performance of a high frequency circuit. Inductance in
the power supply leads can contribute to resonant circuits that
produce peaking in the amplifier’s response. In addition, if large
current transients must be delivered to the load, then bypass ca-
pacitors (typically greater than 1 µF) will be required to provide
the best settling time and lowest distortion. Although the rec-
ommended 0.1 µF power supply bypass capacitors will be suffi-
cient in most applications, more elaborate bypassing (such as
using two paralleled capacitors) may be required in some cases.
If there is a nonzero voltage present on the amplifier’s output
at the time it is switched to the disabled state, some additional
decay time will be required for the output voltage to relax to
zero. The total time for the output to go to zero will generally
be about 250 ns and is somewhat dependent on the load
impedance.
CAPACITIVE LOADS
When used with the appropriate feedback resistor, the ADEL2020
can drive capacitive loads exceeding 1000 pF directly without
oscillation. Another method of compensating for large load ca-
pacitance is to insert a resistor in series with the loop output. In
most cases, less than 50 Ω is all that is needed to achieve an
extremely flat gain response.
OFFSET NULLING
A 10 kΩ pot connected between Pins 1 and 5, with its wiper
connected to V+, can be used to trim out the inverting input
current (with about ±20 µA of range). For closed-loop gains
above about 5, this may not be sufficient to trim the output off-
set voltage to zero. Tie the pot’s wiper to ground through a
large value resistor (50 kΩ for ±5 V supplies, 150 kΩ for ±15 V
supplies) to trim the output to zero at high closed-loop gains.
OPERATION AS A VIDEO LINE DRIVER
The ADEL2020 is designed to offer outstanding performance at
closed-loop gains of one or greater. At a gain of 2, theADEL2020
makes an excellent video line driver. The low differential gain
and phase errors and wide –0.1 dB bandwidth are nearly inde-
pendent of supply voltage and load. For applications requiring
widest 0.1 dB bandwidth, it is recommended to use 715 Ω feed-
back and gain resistors. This will result in about 0.05 dB of
peaking and a –0.1 dB bandwidth of 30 MHz on ±15 V supplies.
DISABLE MODE
By pulling the voltage on Pin 8 to common (0 V), the ADEL2020
can be put into a disabled state. In this condition, the supply
current drops to less than 2.8 mA, the output becomes a high
impedance, and there is a high level of isolation from input to
output. In the case of a line driver for example, the output im-
pedance will be about the same as for a 1.5 kΩ resistor (the
feedback plus gain resistors) in parallel with a 13 pF capacitor
(due to the output) and the input to output isolation will be bet-
ter than 50 dB at 10 MHz.
Leaving the disable pin disconnected (floating) will leave the
part in the enabled state.
