Typical Performance Curves
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.
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
1250
pull-down resistor to the most negative supply. In an
application where the load is connected to V
S
- the output
voltage can swing to within 200mV of V
S
-. 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 1250
resistor and any external pull-down
resistor. If R
L
were 150
then it and the 1250
internal
resistor limit the maximum negative swing to
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 820
external pull-down resistor. This resistor is in parallel with the
internal 1250
resistor. This will increase the negative swing
to
Or -1.16V
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 150
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 820
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
