PGA300EVM-034: PGA300 mode switch

Part Number: PGA300EVM-034


Hi

I'm using PGA300EVM-034,and I can't get the output of TP30(OUT).I can see the nomal graph from "ADC Graph" page in OWI mode,with my input of pressure.Then I click the "OWI mode" button on the upper left corner, it is switched to "Compensation mode",but the voltage of TP30 just changes to 0.67V, and keep this voltage no matter how much pressure I input. Why can't I get the output from TP30? Do I need to adjust the jumper when the device is switched to Compensation mode?

 

Thanks & Best regards

    Hi Jiannan,

    You will need to make sure that the jumper configuration is set for voltage output mode on the EVM. You can refer to the EVM user's guide jumper settings tables: 

    If the jumpers are set properly and you still do not see the proper output, you may have some of the EEPROM settings set improperly for your application. Please share the EEPROM configurations that you are using.

    Regards,
