ADS131M04: Gain Error inconsistency in datasheet

Part Number: ADS131M04
Other Parts Discussed in Thread: ADS131M06

Tool/software:

Hi all,

I'm looking at the ADS131M04 vs ADS131M06. The gain error on the M04 variant is quoted as +/-0.1%, and it's quoted as +/-0.3% on the M06 variant (6.5 Electrical Characteristics, ADC performance). In both datasheets, Figure 6-9 - Gain Error vs Temperature - seems identical between the two parts, showing an upper bound of 0.25% error or so. This would be within spec for gain error on the M06 but not the M04.

This looks like an inconsistency. Could you confirm that this is an error in the datasheet? Or is there a different way to interpret the values?

  • Hi Vladimir Kvitnevskiy,

    The plots in the figure 6-9 in both ADS131M04 and ADS131M06 datasheet look same, but I believe the plot in the figure 6-9 in the ADS131M04 datasheet is incorrect after I looked the char data. I would check with the colleague who worked on the datasheet and get it back to you early next week because he is on vacation now.

    BR,
