ISL28127 and ISL28227 SPICE Model
Figure 40 shows the SPICE model schematic and Figure 41 shows
the net list for the ISL28127 and ISL28227 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, Slew Rate, CMRR, Gain
and Phase. The DC parameters are VOS, IOS, total supply current
and output voltage swing. The model does not model input bias
current. The model uses typical parameters given in the “Electrical
Specifications” Table beginning on page 4. The AVOL is adjusted
for 128dB with the dominate pole at 5Hz. The CMRR is set higher
than the “Electrical Specifications” Table to better match design
simulations (150dB, f = 50Hz). The input stage models the actual
device to present an accurate AC representation. The model is
configured for ambient temperature of +25°C.
Figures 42 through 57 show the characterization vs simulation
results for the Noise Voltage, Closed Loop Gain vs Frequency,
Closed Loop Gain vs Rf/Rg, Closed Loop Gain vs R
Gain vs C
Phase and Simulated CMRR vs Frequency.
