PDMAX for each amplifier can be calculated using Equation 2:
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
ISL28118M SPICE Model
Figure 50 shows the SPICE model schematic and Figure 51 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, 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 4. 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.
Figures 52 through 66 show the characterization vs simulation
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.
