ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. Test conditions are V+ = 2.25V to 5.5V, VMOD = 0V to VSET,
DIVCODE = 0 to 15 (NDIV = 1 to 16,384), RSET = 50k to 800k, RLOAD = 5k, CLOAD = 5pF unless otherwise noted.
