Unipolar adjustment prodedure
(i) Apply continuous convert pulses at intervals long enough
to allow a complete conversion and monitor the digital
outputs.
(ii) Apply full-scale minus 1.5LSB to A
and adjust off-set until
the 8 bit (LSB) output just flickers between 0 and 1 with all
other bits at 0.
(iii) Apply 0.5LSB) to A
and adjust zero until 8 bit just flickers
between 0 and 1 with all other bits at 1.
