ELECTRICAL CHARACTERISTICS (continued)
(AVDD = +4.75V to +5.25V, DVDD = +2.70V to +5.25V, VAGNDS = VAGND = VDGND = 0V, VREFIO = internal reference, CRDC = 4 x
33µF, CREFIO = 0.1µF, CAVDD = 4 x 0.1µF || 10µF, CDVDD = 3 x 0.1µF || 10µF; all digital inputs at DVDD or DGND, unless otherwise
noted, fSAMPLE = 250ksps. TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
