Power Dissipation
It is possible to exceed the +150°C maximum junction
temperature 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)
where:
TMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
PDMAX = Maximum power dissipation of 1 amplifier
VS = Total supply voltage
IqMAX = Maximum quiescent supply current of 1 amplifier
VOUTMAX = Maximum output voltage swing of the application
ISL28177 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, Gain and Phase. The
DC parameters are, VOS, 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 140dB with the dominant pole at 0.075Hz. The CMRR
is set 145dB, fcm = 500kHz. The input stage models the actual
device to present an accurate AC representation. The model is
configured for ambient temperature of +25°C.
results for the Noise Voltage, Closed Loop Gain vs Frequency,
Small Signal 0.1V Step, Large Signal 5V Step Response, Open
Loop Gain Phase, CMRR, Unity Gain Frequency Response vs CL
and Output Voltage Swing for ±15V supplies.
