ADC SCALING AND OFFSET
The ADC can be customized to monitor a particular range
of bias current by programming Register 0. Bits 3 and 2
control the scaling of the ADC while bits 1 and 0 control the
ADC offset. The four graphs (Figures 4, 5, 6, & 7) illustrate
the ADC scale values, according to the two bit code. In
each Graph the curves are differentiated by the ADC offset
values. Note: if using I
BIASP
with the maximum current
option set to 10 mA, divide the x-axis value by 10 (i.e. 75
= 7.5, etc.).
These combinations of scales and offsets allow the reso-
lution to be maximized over a given range of current. For
example, if the bias current is known to be in the range of
30mA to 70mA the choice would be the Half scale graph
(code 10
BIN
) and the
offset curve (code 01
BIN
) to
maximize the resolution of the ADC.
Note that these graphs assume a full scale bias current of
100mA. When the ADC is configured to receive input from
the EXT TEMP pin full scale current becomes 390.6μA,
which limits the internal 1/256 scale factor between bias
current and the ADC input current.
