Hi,
I want to know about the internal clock oscillator(275kHz) of ADS1110.
What is the tolerance of the internal clock?
Best regards,
Seishin

Seishin,
The oscillator clock tolerance can be seen by looking at the tolerance to the data rate. The two are directly linked. In the specification, the data rate has a max variability of +28% and -25%. The clock would have the same max variability.
I would also note that there is a temperature dependence on the data rate/clock that can be seen on one of the typical characteristics graphs on page 6 of the datasheet.
