ISL28107, ISL28207, ISL28407 SPICE Model

Figure 56 shows the SPICE model schematic, and Figure 57 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. AVOL is adjusted for 155dB with the

dominant pole at 0.01Hz. CMRR is set (145dB, fcm = 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 58 through 68 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.
