The EL2160C consumes typically 8.5mA and maximum
11.0mA. The worst case power in an IC occurs when the
output voltage is at half supply, if it can go that far, or its
maximum values if it cannot reach half supply. If we set
the two PDMAX equations equal to each other, and solve
for VS, we can get a family of curves for various loads
and output voltages according to:
The following curves show supply voltage (±VS) vs
RLOAD for various output voltage swings for the 2 dif-
ferent packages. The curves assume worst case
conditions of TA = +85°C and IS = 11mA.
The curves do not include heat removal or forcing air, or
the simple fact that the package will probably be
attached to a circuit board, which can also provide some
form of heat removal. Larger temperature and voltage
ranges are possible with heat removal and forcing air
past the part.
Current Limit
The EL2160C has an internal current limit that protects
the circuit in the event of the output being shorted to
ground. This limit is set at 100mA nominally and
reduces with junction temperature. At a junction temper-
ature of 150°C, the current limits at about 65mA. If the
output is shorted to ground, the power dissipation could
be well over 1W. Heat removal is required in order for
the EL2160C to survive an indefinite short.
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 resis-
tor will decouple the EL2160C from the capacitive cable
and allow extensive capacitive drive. However, other
applications may have high capacitive loads without ter-
mination resistors. In these applications, an additional
small value (5
–50) resistor in series with the output
will eliminate most peaking. The gain resistor, RG, can
be chosen to make up for the gain loss created by this
additional series resistor at the output.
