ELECTRICAL CHARACTERISTICS (continued)
VAVDD = 4.75V to 5.25V, VDVDD = +2.7V 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.
TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
