the current drive of the EL2073C remains a minimum of
50mA at low temperatures. The EL2073C is current-
limited at the output, allowing it to withstand momen-
tary shorts to ground. However, power dissipation with
the output shorted can be in excess of the power-dissipa-
tion capabilities of the package.
Capacitive Loads
Although the EL2073C has been optimized to drive
resistive loads as low as 50
, capacitive loads will
decrease the amplifier's phase margin which may result
in peaking, overshoot, and possible oscillation. For opti-
mum AC performance, capacitive loads should be
reduced as much as possible or isolated via a series out-
put resistor. Coax lines can be driven, as long as they are
terminated with their characteristic impedance. When
properly terminated, the capacitance of coaxial cable
will not add to the capacitive load seen by the amplifier.
Capacitive loads greater than 10pF should be buffered
with a series resistor (Rs) to isolate the load capacitance
from the amplifier output. A curve of recommended Rs
vs Cload has been included for reference. Values of Rs
were chosen to maximize resulting bandwidth without
peaking.
Printed-Circuit Layout
As with any high-frequency device, good PCB layout is
necessary for optimum performance. Ground-plane con-
struction is highly recommended, as is good power
supply bypassing. A 1F–10F tantalum capacitor is
recommended in parallel with a 0.01F ceramic capaci-
tor. All lead lengths should be as short as possible, and
all bypass capacitors should be as close to the device
pins as possible. Parasitic capacitances should be kept to
an absolute minimum at both inputs and at the output.
Resistor values should be kept under 1000
to 2000
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 parasitic inductance. Simi-
larly, capacitors should be low-inductance for best
performance. If possible, solder the EL2073C directly to
the PC board without a socket. Even high quality sockets
add parasitic capacitance and inductance which can
potentially degrade performance. Because of the degra-
dation of AC performance due to parasitics, the use of
surface-mount components (resistors, capacitors, etc.) is
also recommended.
