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