回复： Problem with ADI AD8304 spice model in Multisim 13

[hxing]

Hi, everyone. I need to simulate AD8304 in Multisim 13, and I used spice model downloaded from Analog Devices .com. But, two errors always appear, and I can't find out the reasons.

All the errors are as follows:

------ Checking SPICE netlist for Design1 - 2014年7月15日, 16:48:20 ------
SPICE Netlist Error in schematic RefDes 'u1', element 'xu1':  Invalid subckt definition name 'ad8304__ad_log_converter__1'
SPICE Netlist Error in schematic RefDes 'u1', element '<unknown>':  Due to errors, the subckt instance 'xu1' will be omitted from the simulation
SPICE Netlist Warning, element 'ad8304__ad_log_converter__1':  Duplicate subckt node name '8'
======= SPICE Netlist check completed, 2 error(s), 1 warning(s) =======

Is there  anyone who has encountered the same errors? Please give me some suggestion!

Thank you!

The circuit composed of AD8304 is as follows:

Hi there,

I can't find the Spice Model on the official website of ADI, but I do find a ad8304.cir file. However, this is not a spice model, it's a netlist file. Besides, this netlist is wrong due to the node assignments. So, which Spice Model are you using right now? Could you please post it here?

Hi, Chen_T.

     I got the same ad8304.cir file from the official website of ADI, and I mistook this file for the Spice Model of ad8304.

When I simulated the circuit above by importing this file into Multisim 13, the identical error appeared. But I haven't worked out 

this problem, so if you got the right spice model, hope you can post it here. Of course, if I get it, I will post it here.

    Thank you for your reply!

   Best regards!

Greetings,

This question have still unsettled. The same indication is displayed when the circuit simulated. 

Please give me a favor, if you know how to work out it!

The circuit and the ad8304.cir are attached as follows:
