ADS1262: Strain Gauge and Wheatstone Bridge reading for pressure sensors, force transducers with sensitivity of 2 mV/V and 1 mV/V

Sarper ONAL

Part Number: ADS1262

Dear Support Team,

We are trying to implement a Wheatstone bridge reading ability to our controller, The sensors that we are willing to read are force transducers, pressure sensors and load cells that have 1mV/V sensitivity. For this purpose, we are planning to use ADS1262IPWR. 

Since it is a 32-bit ΔΣ ADC, and it has 128 gain on its PGA I believe we can read this type of sensors with ADS1262.  Please let me know If I can read such sensors with ADS126x, I wonder if this component is suitable for this purpose? 

Best Regards.

    Hi Sarper,

    The ADS1262 is definitively suitable for Wheatstone bridge measurements.

    The integrated PGA in the ADS1262 will only provide gains up to 32 V/V; however, it still provides very high resolution measurements for small-signals. If you decide to excite the bridge with a 5V source, you can feed this voltage directly to the ADC's reference input to create a ratiometric measurement. If you need to use a larger excitation voltage, then you'll need to divide it down to 5V before supplying it to the ADC.

    Best regards,
    Chris
