General Description

gain_bandwidth product
(EL2211C, EL2311C, &
EL2411C)
• Stable at gain of 1 and 50MHz
gain_bandwidth product
(EL2210C, EL2310C, &
EL2410C)
• 130V/µs slew rate
• Drives 150W load to video levels
• Inputs and outputs operate at
negative supply rail
• ±5V or +10V supplies
This family of dual, triple, and quad operational amplifiers built using
Elantec's Complementary Bipolar process offers unprecedented high
frequency performance at a very low cost. They are suitable for any
application such as consumer video, where traditional DC perfor-
mance specifications are of secondary importance to the high
frequency specifications. On ±5V supplies at a gain of +1 the
EL2210C, EL2310C, and EL2410C will drive a 150W load to +2V,---
-1V with a bandwidth of 50MHz and a channel-to-channel isolation of
60dB or more. At a gain of +2, the EL2211C, EL2311C, and EL2411C
will drive a 150W load to +2V, -1V with a bandwidth of 100MHz with
the same channel-to-channel isolation. All four achieve 0.1dB band-
width at 5MHz.
The power supply operating range is fixed at ±5V or +10/0V. In single
supply operation the inputs and outputs will operate to ground. Each
amplifier draws only 7mA of supply current.
• -60dB isolation at 4.2MHz
Applications
• Consumer video amplifiers
• Active filters/integrators
• Cost-sensitive applications
• Single supply amplifiers

Low Cost, Dual, Triple and Quad Video Op Amps
Application Information
The negative swing can be increased by adding an exter-
nal resistor of appropriate value from the output to the
negative supply. The simplified block diagram shows an
820W external pull-down resistor. This resistor is in par-
allel with the internal 1250W resistor. This will increase
the negative swing to
Product Description
The EL2210C, EL2310C, and EL2410C are dual, triple,
and quad operational amplifiers stable at a gain of 1. The
EL2211C, EL2311C, and EL2411C are dual, triple, and
quad operational amplifiers stable at a gain of 2. All six
are built on Elantec's proprietary complimentary process
and share the same voltage mode feedback topology.
This topology allows them to be used in a variety of
applications where current mode feedback amplifiers are
not appropriate because of restrictions placed on the
feedback elements. These products are especially
designed for applications where high bandwidth and
good video performance characteristics are desired but
the higher cost of more flexible and sophisticated prod-
ucts are prohibitive.

Power Dissipation and Loading
Without any load and a 10V supply difference the power
dissipation is 70mW per amplifier. At 12V supply dif-
ference this increases to 105mW per amplifier. At 12V
this translates to a junction temperature rise above ambi-
ent of 33°C for the dual and 40°C for the quad amplifier.
When the amplifiers provide load current the power dis-
sipation can rapidly rise.
Power Supplies
These amplifiers are designed to work at a supply volt-
age difference of 10V to 12V. These amplifiers will
work on any combination of ± supplies. All electrical
characteristics are measured with ±5V supplies. Below
9V total supply voltage the amplifiers’ performance will
degrade dramatically. The quiescent current is a direct
function of total supply voltage. With a total supply volt-
age of 12V the quiescent supply current will increase
from a typical 6.8mA per amplifier to 10mA per
amplifier.
In ±5V operation each output can drive a grounded
150W load to more than 2V. This operating condition
will not exceed the maximum junction temperature limit
as long as the ambient temperature is below 85°C, the
device is soldered in place, and the extra pull-down
resistor is 820W or more.
If the load is connected to the most negative voltage
(ground in single supply operation) you can easily
exceed the absolute maximum die temperature. For
example the maximum die temperature should be
150°C. At a maximum expected ambient temperature of
85°C, the total allowable power dissipation for the SO8
package would be:
Output Swing vs Load
Please refer to the simplified block diagram. These
amplifiers provide an NPN pull-up transistor output and
a passive 1250W pull-down resistor to the most negative
supply. In an application where the load is connected to
VS- the output voltage can swing to within 200mV of
VS-. In split supply applications where the DC load is
connected to ground the negative swing is limited by the
voltage divider formed by the load, the internal 1250W
resistor and any external pull-down resistor. If RL were
150W then it and the 1250W internal resistor limit the
maximum negative swing to
150 – 85
160°C/W
P
= ------------------------= 361mW
D
At 12V total supply voltage each amplifier draws a max-
imum of 10mA and dissipates 12V * 10mA = 120mW or
240mW for the dual amplifier. Which leaves 121mW of
increased power due to the load. If the load were 150W
connected to the most negative voltage and the maxi-
mum voltage out were VS- +1V the load current would
be 6.67mA. Then an extra 146mW ((12V - 1V) *
6.67mA * 2) would be dissipated in the EL2210C or

EL2211C. The total dual amplifier power dissipation
would be 146mW + 240mW = 386mW, more than the
maximum 361mW allowed. If the total supply differ-
ence were reduced to 10V, the same calculations would
yield 200mW quiescent power dissipation and 120mW
due to loading. This results in a die temperature of
143°C (85°C + 58°C).
Printed-Circuit Layout
The EL2210C/EL2211C/EL2310C/EL2311C/
EL2410C/EL2411C are well behaved, and easy to apply
in most applications. However, a few simple techniques
will help assure rapid, high quality results. As with any
high-frequency device, good PCB layout is necessary
for optimum performance. Ground-plane construction is
highly recommended, as is good power supply bypass-
ing. A 0.1µF ceramic capacitor is recommended for
bypassing both supplies. Lead lengths should be as short
as possible, and bypass capacitors should be as close to
the device pins as possible. For good AC performance,
parasitic capacitances should be kept to a minimum at
both inputs and at the output. Resistor values should be
kept under 5kW because of the RC time constants associ-
ated with the parasitic capacitance. Metal-film and
carbon resistors are both acceptable, use of wire-wound
resistors is not recommended because of their parasitic
inductance. Similarly, capacitors should be low-induc-
tance for best performance.
In the above example, if the supplies were split ±6V and
the 150W loads were connected to ground, the load
induced power dissipation would drop to 66.7mW
(6.67mA * (6 - 1) * 2) and the die temperature would be
below the rated maximum.
Video Performance
Following industry standard practices (see EL2044C
applications section) these six devices exhibit good dif-
ferential gain (dG) and good differential phase (dP) with
±5V supplies and an external 820W resistor to the nega-
tive supply, in a gain of 2 configuration. Driving 75W
back terminated cables to standard video levels (1.428V
at the amplifier) the EL2210C, EL2310C, and EL2410C
have dG of 0.1% and dP of 0.2°. The EL2211C,
EL2311C, and EL2411C have dG of 0.04% and dP of
0.15°.
Due to the negative swing limitations described above,
inverted video at a gain of 2 is just not practical. If
swings below ground are required then changing the
extra 820W resistor to 500W will allow reasonable dG
and dP to approximately -0.75mV. The EL2211C,
EL2311C, and EL2411C will achieve approximately
0.1%/0.4° between 0V and -0.75V. Beyond -0.75V dG
and dP get worse by orders of magnitude.
Differential gain and differential phase are fairly con-
stant for all loads above 150W. Differential phase
performance will improve by a factor of 3 if the supply
voltage is increased to ±6V.
Output Drive Capability
None of these devices have short circuit protection. Each
output is capable of more than 100mA into a shorted
output. Care must be used in the design to limit the out-
put current with a series resistor.
