LMP8602: PSpice Model Pinout

Jejomar Ildefonso

Part Number: LMP8602

Hi Team,

Can we ask for your assistance in checking the PSpice model we have for LMP8602? Our customer used the published PSpice model on the LMP8602 product page but it seems that the pinouts of the model do not match the datasheet.

Here is an image of the PSpice model downloaded from the LMP8602 product page compared with the pinout configuration of the LMP8602 part from the data sheet.  As can be seen, most of the pins are different compared with each other.



They've initially ran a simulation using the model but they were getting weird results.

Please let me know if you need further information. Thanks in advance!


Kind Regards,

Jejomar

    Hello Jejomar,

    Many of the spice models were not designed with numerical pinouts that match the real device. The model symbol's pin name is what should be dictating circuit set up.

    In this case, the pin names A1 and A2 (also VS and GND) were also changed from datasheet. In the model's netlist (lmp8602.lib), there is an explanation of how the model pin names match up with real device pin names.

    Performing a quick test by modifying the PSPICE reference design from the product page proves that this key is correct. RF = A1 (output of first stage amplifier), IN2=A2 (inputs to the second stage amplifier), Vs=VCC, GND=VEE, and so on.

    We're sorry for this inconvenience and we hope to resolve this confusion soon.

    Sincerely,

    Peter
