ELECTRICAL CHARACTERISTICS The q denotes specifications which apply over the full operating
temperature range, otherwise specifications are at T A = 25 ° C. V CC = 16V, V BAT = 8V, V MAX (maximum operating V CC ) = 28V,
R S2 = R S3 = 200 ? (see Block Diagram), V CLN = V CC . No load on any outputs unless otherwise noted.
