General Description
The EL2260C EL2460C are dual quad current feedback opera-
tional amplifiers with
b
3 dB bandwidth of 130 MHz at a gain
of
a
2 Built using the Elantec proprietary monolithic comple-
mentary bipolar process these amplifers use current mode feed-
back to achieve more bandwidth at a given gain than a conven-
tional voltage feedback operational amplifier
The EL2260C EL2460C are designed to drive a double termi-
nated 75
X coax cable to video levels Differential gain and
phase are excellent when driving both loads of 500
X (
k
0 01%
k
0 01 ) and double terminated 75
X cables (0 025% 0 1 )
The amplifiers can operate on any supply voltage from 4V
(
g
2V) to 33V (
g
16 5V) yet consume only 7 5 mA per amplifier
at any supply voltage Using industry standard pinouts the
EL2260C is available in 8-pin P-DIP and 8-pin SO packages
while the EL2460C is available in 14-pin P-DIP and 14-pin SO
packages
Elantec's facilities comply with MIL-I-45208A and offer appli-
cable quality specifications For information on Elantec's pro-
cessing see the Elantec document QRA-1 Elantec's Process-

Applications Information
Product Description
The EL2260C EL2460C are dual and quad cur-
rent mode feedback amplifiers that offer wide
bandwidths and good video specifications at
moderately low supply currents They are built
using Elantec's proprietary complimentary bipo-
lar process and are offered in industry standard
pin-outs Due to the current feedback architec-
ture the EL2260C EL2460C closed-loop 3 dB
bandwidth is dependent on the value of the feed-
back resistor First the desired bandwidth is se-
lected by choosing the feedback resistor R
F
and
then the gain is set by picking the gain resistor
R
G
The curves at the beginning of the Typical
Performance Curves section show the effect of
varying both R
F
and R
G
The 3 dB bandwidth is
somewhat dependent on the power supply volt-
age As the supply voltage is decreased internal
junction capacitances increase causing a reduc-
tion in closed loop bandwidth To compensate for
this smaller values of feedback resistor can be
used at lower supply voltages
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 plane construction is high-
ly recommended Lead lengths should be as short
as possible below
The power supply pins
must be well bypassed to reduce the risk of oscil-
lation A 1 0
mF tantalum capacitor in parallel
with a 0 01
mF 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 (see Capacitance at the Inverting
Input section) 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 in-
ductance Similarly capacitors should be low in-
ductance for best performance Use of sockets
particularly for the SO packages
should be
avoided Sockets add parasitic inductance and ca-
pacitance which will result in peaking and over-
shoot
Capacitance at the Inverting Input
Due to the topology of the current feedback am-
plifier stray capacitance at the inverting input
will affect the AC and transient performance of
the EL2260C EL2460C when operating in the
non-inverting configuration
The characteristic
curve of gain vs frequency with variations of
C
IN
b
emphasizes this effect The curve illus-
trates how the bandwidth can be extended to be-
yond 200 MHz with some additional peaking
with an additional 2 pF of capacitance at the
V
IN
b
pin for the case of A
V
e a
2 Higher val-
ues of capacitance will be required to obtain simi-
lar effects at higher gains
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

a
2
This value of feedback resistor yields extremely
flat frequency response with little to no peaking
out to 130 MHz As is the case with all current
feedback amplifiers wider bandwidth at the ex-
pense of slight peaking can be obtained by re-
ducing the value of the feedback resistor Inverse-
ly larger values of feedback resistor will cause
rolloff to occur at a lower frequency By reducing
R
F
to 430
X
bandwidth can be extended to
170 MHz with under 1 dB of peaking Further
reduction of R
F
to 360
X increases the bandwidth
to 195 MHz with about 2 5 dB of peaking See
the curves in the Typical Performance Curves
section which show 3 dB bandwidth and peaking
vs frequency for various feedback resistors and
various supply voltages
Bandwidth vs Temperature
Whereas many amplifier's supply current and
consequently 3 dB bandwidth drop off at high
temperature
the EL2260C EL2460C were de-
signed to have little supply current variations
with temperature An immediate benefit from
this is that the 3 dB bandwidth does not drop off
drastically with temperature With V

If a single supply is desired values from
a
4V to
a
30V 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
EL2260C EL2460C
Settling Characteristics
The EL2260C EL2460C offer superb settling
characteristics to 0 1% typically in the 35 ns to
40 ns range There are no aberrations created
from the input stage which often cause longer
settling times in other current feedback amplifi-
ers The EL2260 EL2460 are not slew rate limit-
ed therefore any size step up to
g
10V gives ap-
proximately the same settling time
As can be seen from the Long Term Settling Er-
ror curve for A
V
e a
1 there is approximately a
0 035% residual which tails away to 0 01% in
about 40
ms This is a thermal settling error
caused by a power dissipation differential (before
and after the voltage step) For A
V
e b
1 due to
the inverting mode configuration this tail does
not appear since the input stage does not experi-
ence the large voltage change as in the non-
inverting mode With A
V
e
b
1 0 01% settling
time is slightly greater than 100 ns
Power Dissipation
The EL2260C EL2460C amplifiers combine both
high speed and large output current drive capa-
bility at a moderate supply current in very small
packages It is possible to exceed the maximum
junction temperature allowed under certain sup-
ply voltage temperature and loading conditions
To ensure that the EL2260C EL2460C remain
within their absolute maximum ratings the fol-
lowing discussion will help to avoid exceeding
the maximum junction temperature
The maximum power dissipation allowed in a
package is determined by its thermal resistance
and the amount of temperature rise according to

In general an amplifier's AC performance de-
grades at higher operating temperature and lower
supply current Unlike some amplifiers such as
the LT1229 and LT1230 the EL2260C EL2460C

maintain almost constant supply current over
temperature so that AC performance is not de-
graded as much over the entire operating temper-
ature range Of course this increase in perform-
ance doesn't come for free Since the current has
increased supply voltages must be limited so
that maximum power ratings are not exceeded
Each amplifier in the EL2260C EL2460C con-
sume typically 7 5 mA and maximum 10 0 mA

output voltage is at half supply if it can go that
far or its maximum value if it cannot reach

Supply Voltage vs Ambient Temperature

The curves do not include heat removal or forc-
ing air or the simple fact that the package will
probably be attached to a circuit board which
can also provide some form of heat removal
Larger temperature and voltage ranges are possi-
ble with heat removal and forcing air past the
part
Current Limit
The EL2260C EL2460C have internal current
limits that protect the circuit in the event of the
output being shorted to ground This limit is set
at 100 mA nominally and reduces with junction
temperature At a junction temperature of 150 C
the current limits at about 65 mA If any one
output is shorted to ground the power dissipa-
tion could be well over 1W and much greater if
all outputs are shorted Heat removal is required
in order for the EL2260C EL2460C to survive an
indefinite short
Channel to Channel Isolation
Due to careful biasing connections within the in-
ternal circuitry of the EL2260C EL2460C excep-
tionally good channel to channel isolation is ob-
tained Isolation is over 70 dB at video frequen-
cies of 4 MHz and over 65 dB up to 10 MHz The
EL2460C isolation is improved an additional
10 dB up to about 5 MHz for amplifiers A to B
and amplifiers C to D Isolation is improved an-
other 8 dB for amplifiers A to C and amplifiers B
to D See the curve in the Typical Performance
Curves section for more detail
Driving Cables and Capacitive Loads
When used as a cable driver double termination
is always recommended for reflection-free per-
formance For those applications the back termi-
nation series resistor will decouple the EL2260C
and EL2460C from the capacitive cable and allow
extensive capacitive drive However other appli-
cations may have high capacitive loads without
termination resistors In these applications an
additional small value (5
X 50X) resistor in se-
ries with the output will eliminate most peaking
The gain resistor R
G
can be chosen to make up
for the gain loss created by this additional series
resistor at the output
