Supply Voltage Range and Single-Supply
Operation
The EL5106 and EL5306 have been designed to operate
with supply voltages having a span of greater than or equal
to 5V and less than 11V. In practical terms, this means that
the EL5106 and EL5306 will operate on dual supplies
ranging from ±2.5V to ±5V. With single-supply, the EL5106
and EL5306 will operate from 5V to 10V.
As supply voltages continue to decrease, it becomes
necessary to provide input and output voltage ranges that
can get as close as possible to the supply voltages. The
EL5106 and EL5306 have an input range which extends to
within 2V of either supply. So, for example, on ±5V supplies,
the EL5106 and EL5306 have an input range which spans
±3V. The output range is also quite large, extending to within
1V of the supply rail. On a ±5V supply, the output is therefore
capable of swinging from -4V to +4V. Single-supply output
range is larger because of the increased negative swing due
to the external pull-down resistor to ground. Figure 16 shows
an AC-coupled, gain of +2, +5V single supply circuit
configuration.
Video Performance
For good video performance, an amplifier is required to
maintain the same output impedance and the same
frequency response as DC levels are changed at the output.
This is especially difficult when driving a standard video load
of 150
Ω, because of the change in output current with DC
level. Previously, good differential gain could only be
achieved by running high idle currents through the output
transistors (to reduce variations in output impedance).
Special circuitries have been incorporated in the EL5106 and
EL5306 to reduce the variation of output impedance with
current output. This results in dG and dP specifications of
0.02% and 0.04°, while driving 150
Ω at a gain of 2.
Output Drive Capability
In spite of its low 1.5mA of supply current per amplifier, the
EL5106 and EL5306 are capable of providing a maximum of
±125mA of output current.
Driving Cables and Capacitive Loads
When used as a cable driver, double termination is always
recommended for reflection-free performance. For those
applications, the back-termination series resistor will
decouple the EL5106 and EL5306 from the cable and allow
extensive capacitive drive. However, other applications may
have high capacitive loads without a back-termination
resistor. In these applications, a small series resistor (usually
between 5
Ω and 50Ω) can be placed in series with the
output to eliminate most peaking.
