    Hello Raviteja,

    Below are the following pin designation descriptions for the pspice model.

    • VCC: positive power supply pin (7V-24V range)
    • VEE: negative power supply pin (GND)
    • VINM: IN- (input pin for signal)
    • VINP: IN+ (input pin for biasing VCM to mid-supply)
    • VOUT: output pin
    • ISET: power amplifier current limit set

    I would recommend using the TINATI model from the link below.

    This model has both transmit and receive, protection scheme, and a signal generator that represents the signal after the 4th order filter stage on the AFE031.  This model also has documentation which I have attached the link below.

    If you do not have TINATI simulation software you can download the free version from the link below.

    Best regards,
