Part Number: INA2181
Other Parts Discussed in Thread: INA181,

Tool/software:

Hey Team,

Can you please check if we have the following PSPICE model internally, or advise us on the closest alternative PSPICE model to use?

  • INA2181A3IDGST

Edit: I see the INA181 model. Is there be anything we should be aware of when simulating the INA2181 with the INA181 model? Any differences?

    Hey Dajon,

    Two separate INA181s can be used and this will still accurately represent behavior. The specifications are all increased proportionally with increasing number of channels. For example IQ doubles for the the two channel.

    The only thing this won’t reflect is the Channel-to-Channel separation, but the offset generated from this is fairly small and is only significant if each channel is measuring bus voltages with large differences in amplitude and/or frequency.

    Sincerely,

    Peter
