Conversion Rate
The
Conversion Rate
selection box (shown in

temperature conversion takes the TMP112 to perform. The user may want to select a slower conversion
time, as shown in
, to make the TMP112 consume less power.

Fault Queue
The fault queue drop-down box allows the user to configure how many faults must be triggered before the
Alert pin is activated, as shown in
. A fault is generated whenever the TMP112 T
HIGH
register is
exceeded by the temperature register. This feature can be useful to prevent the TMP112 from triggering
on temperature spikes that the user may not want to trigger with the Alert pin.
