Tool/software:

Hi team,

My customer is evaluating ADCS7476, and there is a question as below:

How many leading zeros on SDATA, three or four? I noticed that the wordings show four leading zeros but the picture shows only three leading zeros (Z2, Z1, Z0).

Does the configuration of ADC121's SDATA be same with ADCS7476? How many leading zeros of ADC121?

Best Regards,

Ryker

Hi Ryker,

Thanks for your patience as we are on holiday. Per the datasheet, it looks like you should be expecting 4 leading zeroes. The diagram may require an update, thanks for noting it, I will let the team know.

Devices like the ADC121S101 have 3 leading zeroes, per the datasheet.

Best regards,

Samiha
