(typical) the device automatically turns ON the outputs
by putting them in a low impedance (normal)
operating state.
Driving Capacitive Loads
As load capacitance increases, the -3dB bandwidth will
decrease and peaking can occur. Depending on the
application, it may be necessary to reduce peaking and
to improve device stability. To improve device stability,
a snubber circuit or a series resistor may be added to
the output of the EL5220T.
A snubber is a shunt load consisting of a resistor in series
with a capacitor. An optimized snubber can improve the
phase margin and the stability of the EL5220T. The
advantage of a snubber circuit is that it does not draw
any DC load current or reduce the gain.
Another method to reduce peaking is to add a series
output resistor (typically between 1Ω to 10Ω).
Depending on the capacitive loading, a small value
resistor may be the most appropriate choice to
minimize any reduction in gain.
Power Dissipation
With the high-output drive capability of the EL5220T
amplifiers, it is possible to exceed the +150°C absolute
maximum junction temperature under certain load
current conditions. It is important to calculate the
maximum power dissipation of the EL5220T in the
application. Proper load conditions will ensure that the
EL5220T junction temperature stays within a safe
operating region.
The maximum power dissipation allowed in a package is
determined according to Equation 1:
where:
TJMAX = Maximum junction temperature
TAMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
PDMAX = Maximum power dissipation allowed
The total power dissipation produced by an IC is the
total quiescent supply current times the total power
supply voltage, plus the power dissipation in the IC
due to the loads, or:
when sourcing, and:
when sinking, where:
i = 1 to 2
(1, 2 corresponds to Channel A, B respectively)
VS = Total supply voltage (VS+ - VS-)
VS+ = Positive supply voltage
VS- = Negative supply voltage
ISMAX = Maximum supply current per amplifier
(ISMAX = EL5220T quiescent current ÷ 2)
VOUT = Output voltage
ILOAD = Load current
Device overheating can be avoided by calculating the
minimum resistive load condition, RLOAD, resulting in
the highest power dissipation. To find RLOAD set the
two PDMAX equations equal to each other and solve for
VOUT/ILOAD. Reference the package power dissipation
