AD8337 / SPICE MODEL Dynamic Range

Hi Vzaz 

The Vgain setting for 0dB gain is -700mV.

Also, can you provide your schematic on LTspice for us to check?

Thanks and regards,

JE

Hello,

Based on Figure 3 of the datasheet it seems to me that at -600mV the gain should already be at 0dB. I tried the model at -700mV as well and it does not make much of a difference. 

Please check below my result and find attached the LTspice model.

Happy to hear your comments. 

Thank you. 

Hi Vzaz ,

Thanks for providing the model and as per checking, there are differences on the response between the model and the datasheet.

The red line represents the SPICE model response.

We will communicate this with the LTspice team and request for a review or creation of the LTspice model.

If you would need the actual response of the part. You can check our evaluation board to test the part according to your expected application.

Hope that helps.

Thanks and regards,

JE

Hello JE,

Thanks for your response. 

As long as the datasheet is accurate, this is fine for me. 

Yes, we will proceed with an evaluation board. 

Shall we leave this thread open until you get a response from LTSPICE team or close it down? 

Thank you for your help.
