Conversion rate bits

The conversion rate bits define the number of executed temperature conversions per time unit.

Additional readouts of the temperature register between conversions are possible but not

recommended because the value is changed only after a conversion is finished.

Values of 125 ms, 250 ms, 1 s and 4 s for a conversion can be configured while the default

rate is set to 4 conversions per second. The following table summarizes the different

configuration settings:

The device immediately starts a conversion after a power-on sequence and provides the first

result after typ. 36 ms (max. 51 ms). A higher power consumption occurs during the actual

conversion while the device stays in the standby mode after a finished conversion until the

next conversion is activated. This is shown in the following figure.
