ADS131M04: We are using this converter to retrieve the dc voltage from the external feed, by blocking the capacitor

rohith Goud

Part Number: ADS131M04

For our experimentation we are removing the block DC option since we have to acquire the direct voltage, Is that is the right way to get the voltage from the sensors? / How exactly we should configure the converter to acquire the DC voltage from the source sensor / Voltage ?

We require support in understanding the Dc voltage data acquisition with ads131m04IPWR.

Hello Rohith,

Thank you for your post.

Please refer to the device data sheet for the acceptable absolute and differential input voltage. The DC block filter option is disabled by default (DCBLOCK[3:0] = 0000b).

Dear Sir/ Madam,

Could you please suggest the example code / reference case of similar kind of questionnaire, Kindly please share the information and documents on coding done for dc data acquisition with the given differential channels.

Best Regards,

Dear Sir,

Do we have single ended ADC with the same package and footprint. we are fine upto 16 bit ADC

Hi Andrews,

Thanks for your reply. I can share the code that we developed using the same library. However, the code doesn't give me the values expected. Please let me know if you can help us.

Thanks,

Rohit.

Dear Andrews,

We have utilized the code earlier , couldn't get the end solution for the same.

Thanks,

Hello Rohith,

The example code is provided as-is. You will need to modify the code to suit your end application.

If you are struggling with acquiring accurate data from the ADC, or the data you are receiving is incomprehensible, please begin a new thread with a specific question and we can review it.
