ADA4941-1 .cir

Original Question: ADA4941-1 .cir by sss

Hi all,

Our customer tryed to simulate the ADA4941-1 with ADIsimPE.
They downloaded the ADA4941 SPICE Macro Model from web linked page .

But the error occured with following error massage.

"*** ERROR *** The circuit is too large to simulate with this version.
Too many analog nodes

Test circuit is the ada4941-1 parts only from "Figure 57. ADA4941-1 Driving the AD7687 ADC" @ datasheet.
What is happens ?

Best regards,
sss

Hi,

The error is normal for too large SPICE models that exceeds circuit nodes limitation of the simulator. What we have to do is to have the .cir file encrypted. What parameters are trying to simulate here? I could have it simulated while waiting for model encryption.

Hi Victor,

Did you remove the first ADA4941 model you imported to ADIsimPe? I believe the simulator is still seeing the previous one, which non-encrypted.

Anyway, try this.

Regards.
