INPUT VOLTAGE RANGE
sample-hold and AID converter should be timed as shown in the timing
diagram. The trigger pulse should be applied at a rate of 70 kHz or less
and should be 100 nanoseconds minimum width.
Apply a precision voltage reference source between the selected analog
input and ground. Adjust the output of the reference source to the value
shown in the Calibration Table for the unipolar zero adjustment (zero +%
LSB) or the bipolar offset adjustment (- FS + % LSB). Adjust the trimming
potentiometer so that the output code fl ickers equally between 1111 1111
1111 and 1111 1111 1110.
Change the output of the precision voltage reference source to the value
shown in the Calibration Table for the unipolar or bipolar gain adjustment
(+ FS - 1% LSB). Adjust the gain trimming potentiometer so that the output
code fl ickers equally between 0000 0000 0001 and 0000 0000 0000.
