Power Dissipation
It is possible to exceed the +150°C maximum junction
temperatures under certain load and power supply conditions. It
is therefore important to calculate the maximum junction
temperature (TJMAX) for all applications to determine if power
supply voltages, load conditions, or package type need to be
modified to remain in the safe operating area. These parameters
are related using Equation 1:
where
PDMAXTOTAL is the sum of the maximum power dissipation of
each amplifier in the package (PDMAX)
TMAX = Maximum ambient temperature
ΘJA = Thermal resistance of the package
where
PDMAX = Maximum power dissipation of 1 amplifier
VS = Total supply voltage
IqMAX = Maximum quiescent supply current of one amplifier
VOUTMAX = Maximum output voltage swing of the application
RL = Load resistance
ISL28118 and ISL28218 SPICE Model
the net list for the SPICE model. The model is a simplified version
of the actual device and simulates important AC and DC
parameters. AC parameters incorporated into the model are: 1/f
and flatband noise voltage, slew rate, CMRR, and gain and phase.
The DC parameters are IOS, total supply current, and output
voltage swing. The model uses typical parameters given in the
“Electrical Specifications” table beginning on page 3. The AVOL is
adjusted for 136dB with the dominant pole at 0.6Hz. The CMRR is
set at 120dB, f = 50kHz. The input stage models the actual device
to present an accurate AC representation. The model is configured
for an ambient temperature of +25°C.
results for the noise voltage, open loop gain phase, closed loop
gain vs frequency, gain vs frequency vs RL, CMRR, large signal
10V step response, small signal 0.1V step, and output voltage
swing ±15V supplies.
