Part Number: ADS1235
Other Parts Discussed in Thread: ADS1220, ADS131M02

Dear team, 

My customer are considering to use ADS1235 for their pressure sensor(Wheatstone Bridge) 

ADS1235 is good for their application but concern point is size issue. they want to control 1 Wheatstone Bridge and 1 temp sensing. 

so they would like to find 1 or 2 ch device with same performance of ADS1235. Is there any device to recommend? 

size limitation is 4x4mm. 

Thank you.

    Hi Nam, Dino,

    We unfortunately do not have a device with similar performance as the ADS1235 that is 4x4mm.

    We do have the ADS131M02 that is in a 3x3mm QFN package, or the ADS1220 in a 3.5x3.5mm QFN. Both of these devices can be used for bridge measurements, though the ADS1220 is better suited given the reference range and the ability to accept a ratiometric reference. But I have seen customers get the M02 to work. In either case, the performance will not be as good as the ADS1235 however

    Let me know if you have any questions about these devices
