in a 14-Pin TSSOP
ELECTRICAL CHARACTERISTICS (continued)
(AV_DD = +4.75V to +5.25V, DV_DD = +2.7V to +5.5V, f_SCL = 1.7MHz (33% duty cycle), f_SAMPLE = 58.6ksps, V_REF = +4.096V, external ref-
erence applied to REF, REFADJ = AV_DD, C_REF = 10µF, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.)
