ELECTRICAL CHARACTERISTICS (continued)
(V_AVDD = +4.75V to +5.25V, V_DVDD = +2.70V to +5.25V, V_AGNDS = V_AGND = V_DGND = 0V, V_REFIO = internal reference, C_RDC = 4 x
33µF, C_REFIO = 0.1µF, C_AVDD = 4 x 0.1µF || 10µF, C_DVDD = 3 x 0.1µF || 10µF; all digital inputs at DVDD or DGND, unless otherwise
noted, f_SAMPLE = 250ksps. T_A = -40°C to +85°C, unless otherwise noted. Typical values are at T_A = +25°C.)
