Standby Mode Operation
The ADC can be put into standby mode to save power. Standby
mode reduces the power to all circuits in the device except the
crystal oscillator amplifier. To enter the standby mode, take the
SCLK signal high and hold it high after SDO/RDY falls. The
converter will remain in standby mode as long as SCLK is held
high. To return to normal operation, take SCLK back low and wait
for the SDO/RDY to fall to indicate that a new conversion has
standby mode.
Supply currents are equal in Standby and Power-down modes
unless a Crystal is used. If the Crystal is used, the Crystal
amplifier is turned ON, even in the standby mode.
Performing Offset Calibration After Standby
Mode
To perform an offset calibration automatically upon returning
from standby, deliver 2 or more additional SCLKs following a
data read cycle, and then set and hold SCLK high. The device will
remain in Standby as long as SCLK remains high. A calibration
cycle will begin once SCLK is brought low again to resume
normal operation. Additional time will be required to perform the
illustrate the details of performing offset calibration after
standby mode.
