W83L771W/G
7.7 Fault Detect
Table 7.7 shows the response of Fault Detection if false connection of DPLUS and DMINUS occurs
after power up. Except response of Table 7.7, if false connection takes place after power up Fault
Detect, the OPEN flag will remain low and get a remote temperature -30℃, the lowest temperature
W83L771W/G could measure.

7.8 Conversion Rate and Moving Average
W83L771W/G provides an embedded moving average into conversion rate selection. The lower
conversation rate can get more average times of measured remote temperature. Using an averaging
temperature attains excellent noise rejection.
