______________________________________________________________________________________
Filter coefficients A1 and B1 are always 1. B3 is limited
to -1, 0, and 1.
Filter coefficients A2, A3, and B2 are stored as 16-bit
two’s complement values in the range of -4 to +4. Filter
coefficients A2 and A3 are stored as -A2 and -A3.
Gain is limited to the following values 24, 22, 20, 2-2, 2-4,
2-6, 2-8, and 2-10. For better gain resolution, adjust the
Fine Gain A/B/C/D Registers at the input of each filter
set. Fine gain adjustment has a resolution of 16 bits and
a gain range of -4 to +4. Set the RECT bit to rectify the
filter output.
Figures 5–8 show the response to a step input of the
default filters used for ADC trimming.
