58.6ksps, 16-Bit, 2-Wire Serial ADC
in a 14-Pin TSSOP
ELECTRICAL CHARACTERISTICS (continued)
(V_AVDD = +4.75V to +5.25V, V_DVDD = +2.7V to +5.5V, f_SCL = 1.7MHz (33% duty cycle), f_SAMPLE = 58.6ksps, V_REF = +4.096V, external
reference applied to REF, REFADJ = AVDD, C_REF = 10µF, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.)
