ADS1261EVM: modes

Part Number: ADS1261EVM
Other Parts Discussed in Thread: ADS1261

Tool/software:

Hi Team,

My customer is testing ADS1261EVM - While testing they noticed, that the chop mode provides a way better noise performance than the ACEX mode (~18,5 Bit ENOB to 22,5 Bit ENOB). Could you elaborate why is this the case? I couldn't find information regarding this.

Thanks,

Daria

    Hi Daria,

    Thanks for providing more information. ADS1261 datasheet has a section 9.4.2 Chop Mode which show the operation of the chop mode on this ADC, but I will send you another document to explain the mechanism with more details via email.

    BR,
