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

ISL28177 SPICE Model
Figure 22 shows the SPICE model schematic and Figure 23 shows
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, I
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, f
device to present an accurate AC representation. The model is
configured for ambient temperature of +25°C.
Figures 24 through 37 show the characterization vs simulation
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 C
and Output Voltage Swing for ±15V supplies.
