8 / 15 page ISL28177 8 FN7859.2 April 5, 2012 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) •PDMAX for each amplifier can be calculated using Equation 2: 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 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, 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. 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 CL and Output Voltage Swing for ±15V supplies.
