Part Number: ADS131B02-Q1 Tool/software: Hi expert,
I need the TCR formula that represents the temperature coefficient. Please provide it in the form of a polynomial modeling the resistance change with temperature variation.
Part Number: ADS131B02-Q1 Hi expert,
Could you pls help to check if one of the AIN0P or AIN0N must be grounded? When customer use the ADC as a differential signal input as shown in the figure(left) below, we can found that the error will be bigger, can…
Part Number: ADS131B02-Q1 Hi expert,
Could you pls help me to confirm whether the ADS131B02 can support one channel for differential input and one for single-ended input?
Thanks a lot.
Part Number: ADS131B02-Q1 Hello support team,
My customer ask the ADS131B02 usage. Due to their MCU issue, the default IO logic setting is low after power up. After MCU power up fully, if MCU set /CS and /SYNC/RESET high and set these pin low again when…
Hello Joachim-san,
Thank you very much for your quick reply.
The results in the excel sheet were with global-chop mode disabled. I thought the offset value I got aligned with the global-chop mode disabled, so I asked my customer to check the offset again…

Hello Kaixin,
that is weird. The schematic looks okay to me.
Could you try sending the STANDBY command before you change the OSR[2:0] registers? And then send the WAKEUP command afterwards? Please read back the OSR[2:0] registers to make sure they have…
Hi Wuerker，
Sorry for delay reply, kindly thanks for your information. Yes, we want use more higher gain, and I will check for the ADS131B02-Q1 series specification. If still had some issue need your support, will reached you again. Thanks!
