Bipolar adjustment prodedure
(i) Apply continuous SC pulses at intervals long enough to
allow a complete conversion and monitor the digital
outputs.
(ii) Apply -(FS -0.5LSB) 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 +(FS -1.5LSB) to A
and adjust gain until the 8 bit
just flickers between 0 and 1 with all other bits at 1.
(iv)Repeat step (ii).
