The filter on and off curves were purposely offset to better show noise performance.

FAULT QUEUE
In order to suppress erroneous ALERT or T_CRIT triggering the LM89 incorporates a Fault Queue. The Fault
Queue acts to insure a remote temperature measurement is genuinely beyond a HIGH, LOW or T_CRIT setpoint
by not triggering until three consecutive out of limit measurements have been made, see Figure 14 . The fault
queue defaults off upon power-up and may be activated by setting bit D0 in the Configuration register (09h) to
“1”.

ONE-SHOT REGISTER
The One-Shot register is used to initiate a single conversion and comparison cycle when the device is in standby
mode, after which the device returns to standby. This is not a data register and it is the write operation that
causes the one-shot conversion. The data written to this address is irrelevant and is not stored. A zero will
always be read from this register.
