Low Cost, Dual, Triple and Quad Video Op
Amps
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 performance
specifications are of secondary importance to the high
frequency specifications. On ±5V supplies at a gain of +1 the
EL2210, EL2310, and EL2410 will drive a 150Ω 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 EL2211,
EL2311, and EL2411 will drive a 150Ω load to +2V, -1V with
a bandwidth of 100MHz with the same channel-to-channel
isolation. All four achieve 0.1dB bandwidth 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.

Application Information
Product Description
The EL2210, EL2310, and EL2410 are dual, triple, and quad
operational amplifiers stable at a gain of 1. The EL2211,
EL2311, and EL2411 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
products are prohibitive.
resistor. If RL were 150Ω then it and the 1250Ω internal
resistor limit the maximum negative swing to
150
V EE = ----------------------------1250 + 150
Or--0.53V
The negative swing can be increased by adding an external
resistor of appropriate value from the output to the negative
supply. The simplified block diagram shows an 820Ω
external pull-down resistor. This resistor is in parallel with the
internal 1250Ω resistor. This will increase the negative swing
to
1250 × 820
V EE = 150 ÷ ----------------------------- + 150
1250 + 820
Or -1.16V
Power Supplies
These amplifiers are designed to work at a supply voltage
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 voltage of 12V the quiescent supply
current will increase from a typical 6.8mA per amplifier to
10mA per amplifier.
Output Swing vs Load
Please refer to the simplified block diagram. These amplifiers
provide an NPN pull-up transistor output and a passive
1250Ω 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 1250Ω resistor and any external pull-down
6
Power Dissipation and Loading
Without any load and a 10V supply difference the power
dissipation is 70mW per amplifier. At 12V supply difference
this increases to 105mW per amplifier. At 12V this translates
to a junction temperature rise above ambient of 33°C for the
dual and 40°C for the quad amplifier. When the amplifiers
provide load current the power dissipation can rapidly rise.
In ±5V operation each output can drive a grounded 150Ω
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 820Ω 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
EL2210/11, EL2310/11, EL2410/11
expected ambient temperature of 85°C, the total allowable
power dissipation for the SO8 package would be:
150 – 85
P D = ------------------------- = 361mW
160°C/W
At 12V total supply voltage each amplifier draws a maximum
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 150Ω connected to the most
negative voltage and the maximum 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
EL2210 or EL2211. The total dual amplifier power
dissipation would be 146mW + 240mW = 386mW, more than
the maximum 361mW allowed. If the total supply difference
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).
In the above example, if the supplies were split ±6V and the
150Ω 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 EL2044
applications section) these six devices exhibit good
differential gain (dG) and good differential phase (dP) with
±5V supplies and an external 820Ω resistor to the negative
supply, in a gain of 2 configuration. Driving 75Ω back
terminated cables to standard video levels (1.428V at the
amplifier) the EL2210, EL2310, and EL2410 have dG of
0.1% and dP of 0.2°. The EL2211, EL2311, and EL2411
have dG of 0.04% and dP of 0.15°.
7
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 820Ω
resistor to 500Ω will allow reasonable dG and dP to
approximately -0.75mV. The EL2211, EL2311, and EL2411
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 constant for
all loads above 150Ω. 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 output current
with a series resistor.
Printed-Circuit Layout
The EL2210/EL2211/EL2310/EL2311/ EL2410/EL2411 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. Groundplane construction is highly recommended, as is good power
supply bypassing. 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 5kΩ because of the RC time constants
associated 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-inductance
for best performance.
