Self-Calibration at Wake-Up
The MAX11212 can be put in self-calibration mode
immediately after wake-up from sleep mode. Self-
calibration at wake-up helps to compensate for tempera-
ture or supply changes if the device is shut down for
extensive periods. To automatically start self-calibration
at the end of sleep mode, all the data bits must be shift-
ed out followed by 25th SCLK edge to pull RDY/DOUT
high, and then on the 26th SCLK keep it high for as long
as shutdown is desired. Once SCLK is pulled back low,
the device automatically performs a self-calibration and,
when the data is ready, the RDY/DOUT output goes low.
See Figure 5. This also achieves the purpose of single
conversions with self-calibration.
