DRV2700: Simulation of abnormal output of DRV2700 with TINA

Annie Liu

Part Number: DRV2700

Hi Team,

The customer's settings are based on the examples given on the official website, including VIN, capacitance, resistance. But the output is limited to below VDD and does not reach the desired magnification. And change the VIN amplitude, GAIN0, GAIN1, the output will not change. But the output frequency is the same as the input.

Then, the customer downloaded it again, and found that the .lib file in the SPICE model given by the official website could not be recognized by TINA, it was an empty file, and a new macro could not be created.

Customer would like to know why there is a problem with .lib?

Hi, Annie,

Could you provide the simulation files that the customer is using for his simulation, please? I'm not aware of any issue on the libraries files.

Best regards,
Luis Fernando Rodríguez S.

Hi Luis,

I apologize for any delay in responding to your post. I have forwarded the question customer. Unfortunately, the customer has not responded to me until now.

You are able to close this thread first. Once the customer has responded to me, I will tell you as soon as possible.

Thanks,
