in a 14-Pin TSSOP
ELECTRICAL CHARACTERISTICS (continued)
(VAVDD = +4.75V to +5.25V, VDVDD = +2.7V to +5.5V, fSCL = 1.7MHz (33% duty cycle), fSAMPLE = 58.6ksps, VREF = +4.096V, external
reference applied to REF, REFADJ = AVDD, CREF = 10µF, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
