ISL28133
ISL28133 SPICE Model
Figure 35 shows the SPICE model schematic and
Figure 36 shows the net list for the ISL28133 SPICE
model. The model is a simplified version of the actual
device and simulates important parameters such as
noise, Slew Rate, Gain and Phase. The model uses
typical parameters from the ISL28133. The poles and
zeros in the model were determined from the actual open
and closed-loop gain and phase response. This enables
the model to present an accurate AC representation of
the actual device. The model is configured for ambient
temperature of +25°C.
Figures 37 through 44 show the characterization vs
simulation results for the Noise Density, Frequency
Response vs Close Loop Gain, Gain vs Frequency vs CL
and Large Signal Step Response (4V).
