program the SD-14531 for lower resolution, allowing the con-
verter to settle faster for step inputs. High precision, faster set-
tling can therefore be obtained simultaneously and automatical-
ly in one unit.
CONNECTING THE SD-14531 TO A P.C. BOARD
The SD-14531 can be attached to a printed circuit board using
hand solder or wave soldering techniques. Limit exposure to
300°C (572°F) max, for 10 seconds maximum.
Since the SD-14531 Series converters contain a CMOS
device, standard CMOS handling procedures should be fol-
lowed.
