PIN Mode
The PIN mode is intended for systems with a linear rela-
tionship between the RSSI input and desired ADC result.
The ADC result transitions between the fine and coarse
ranges with hysteresis, as shown in Figure 6.
In PIN mode, the thresholds between coarse and fine
mode are a function of the number of right-shifts being
used. With the use of right-shifting, the fine mode full scale
is programmed to (1/2nth) of the coarse mode full scale.
The DS1884 now auto ranges to choose the range that
gives the best resolution for the measurement. Table 3
shows the threshold values for each possible number of
right-shifts.
