MAX11212
Data Read Followed by Sleep Mode
The MAX11212 can be put into sleep mode to save
power between conversions. To activate the sleep mode,
idle the SCLK high any time after the RDY/DOUT output
goes low (that is, after conversion data is available). It is
not required to read out all 18 bits before putting the part
in sleep mode. Sleep mode is activated after the SCLK
is held high (see Figure 4). The RDY/DOUT output is
pulled high once the device enters sleep mode. To come
out of sleep mode, pull SCLK low. After the sleep mode
is deactivated (when the device wakes up), conversion
starts again and RDY/DOUT goes low, indicating the
next conversion data is available. See Figure 4.
Single-Conversion Mode
For operating the MAX11212 in single-conversion mode,
activate and deactivate sleep mode between conver-
sions as described in the Data Read Followed by Sleep
Mode section). Single-conversion mode reduces power
consumption by shutting down the device when idle
between conversions. See Figure 4.
