Hi,

Developing a Battery low side load sensing product.

+/- 1000 amp, 0.05 milli ohm shunt.

+/- 0.4% is the overall accuracy requirement of the system. Shunt accuracy is +/- 0.2%.

Is ADS1014L, the right part ? if not please suggest right part

Requirements are in the attached image.

Thanks,

Anil

Hi Anil,

+/- 50mV is a rather small signal for the ADS1014L.

You might want to consider using an amplifier to gain up your signal or look for an ADC with an internal PGA with higher gain.

You could also consider taking a look at TI's current sensing products such as the INA226 data sheet, product information and support | TI.com.

Feel free to use our parametric search tool to narrow down ADC better suited for your application:

Best Regards,

Angel
