Figure 4 provide a convenient way to see if the device will
overheat. The maximum safe power dissipation can be
found graphically, based on the package type and the
ambient temperature. By using the previous equation, it is a
simple matter to see if P

to observe the recommended derating curves shown in
Figure 3 and Figure 4.

Unused Amplifiers
It is recommended that any unused amplifiers in a dual and
a quad package be configured as a unity gain follower. The
inverting input should be directly connected to the output
and the non-inverting input tied to the ground plane.
Driving Capacitive Loads
The EL5210 and EL5410 can drive a wide range of
capacitive loads. As load capacitance increases, however,
the -3dB bandwidth of the device will decrease and the
peaking increase. The amplifiers drive 10pF loads in parallel
with 1kΩ with just 1.2dB of peaking, and 100pF with 6.5dB of
peaking. If less peaking is desired in these applications, a
small series resistor (usually between 5Ω and 50Ω) can be
placed in series with the output. However, this will obviously
reduce the gain slightly. Another method of reducing peaking
is to add a "snubber" circuit at the output. A snubber is a
shunt load consisting of a resistor in series with a capacitor.
Values of 150Ω and 10nF are typical. The advantage of a
snubber is that it does not draw any DC load current or
reduce the gain.
Power Supply Bypassing and Printed Circuit
Board Layout
The EL5210 and EL5410 can provide gain at high frequency.
As with any high-frequency device, good printed circuit
board layout is necessary for optimum performance. Ground
plane construction is highly recommended, lead lengths
should be as short as possible and the power supply pins
must be well bypassed to reduce the risk of oscillation. For
normal single supply operation, where the V
connected to ground, a 0.1µF ceramic capacitor should be
placed from V
capacitor should then be connected in parallel, placed in the
region of the amplifier. One 4.7µF capacitor may be used for
multiple devices. This same capacitor combination should be
placed at each supply pin to ground if split supplies are to be
used.
