PCF8549 (see Fig.14). The coefficients are selected by the two bits TC[1 : 0]. Table 6 shows the typical values of the
different temperature coefficients. The coefficients are proportional to the programmed V

Bias value:
The bias voltage levels are set in the ratio of R

R giving a
bias system. The resulting bias levels
are shown in table 5.
Different multiplex rates require different factors n (see Table 4). This is programmed by BS[2 : 0]. For MUX 1 : 65 the
optimum bias value n is given by:
