Other Parts Discussed in Thread: ADS5263

Hello,

My customer uses the ADS5263 and has a question.

There is no data at less than 3500LSB and more than 62000LSB in the Fig.36, 37.

Does it possible to use in a range less than 3500LSB and more than 62000LSB?

Regards,

Hi,

Sorry for the delay, we had a small issue on our side.

To answer your question, yes it is possible to use the ADC in a range less than code 3500 and greater than 62000 as these codes represent input levels that are within the full scale-range of the 16-bit converter. However, at these code values, the ADC is operating within ~1/2 dB of its full-scale range and a degradation in noise performance is expected.

Regards,

Christian
