Model
Figure 54 shows the SPICE model schematic and
Figure 55 shows the net list for the ISL28107, ISL28207
and ISL28407 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 uses typical parameters given in the “Electrical
Specifications” Table beginning on page 6. The AVOL is
adjusted for 155dB with the dominate pole at 0.01Hz.
The CMRR is set (145dB, f_cm = 100Hz). The input stage
models the actual device to present an accurate AC
representation. The model is configured for ambient
temperature of +25°C.
Figures 56 through 66 show the characterization vs
simulation results for the Noise Voltage, Closed Loop
Gain vs Frequency, Closed Loop Gain vs RL, Large Signal
Step Response, Open Loop Gain Phase and Simulated
CMRR vs Frequency.
