Thus, for a gain of three or more the fader has a noise as
good as an op-amp. The only trade-off is that the dynamic
range of the input is reduced by the gain due to the
nonlinearity caused by gained-up output signals.
Power Dissipation
Peak die temperature must not exceed 150°C. This allows
75°C internal temperature rise for a 75°C ambient. The
EL4095 in the 14-pin PDIP package has a thermal
resistance of 65°C/W, and can thus dissipate 1.15W at a
75°C ambient temperature. The device draws 20mA
maximum supply current, only 600mW at ±15V supplies, and
the circuit has no dissipation problems in this package.
The SO-14 surface-mount package has a 105°C/W thermal
resistance with the EL4095, and only 714mW can be
dissipated at 75°C ambient temperature. The EL4095 thus
can be operated with ±15V supplies at 75°C, but additional
dissipation caused by heavy loads must be considered. If
this is a problem, the supplies should be reduced to ±5V to
±12V levels.
The output will survive momentary short-circuits to ground,
but the large available current will overheat the die and also
potentially destroy the circuit’s metal traces. The EL4095 is
reliable within its maximum average output currents and
operating temperatures.
EL4095 Macromodel
This macromodel is offered to allow simulation of general
EL4095 behavior. We have included these characteristics:
These will give a good range of results of various operating
conditions, but the macromodel does not behave identically
