Temperature Sensing, and GPIO Ports
ELECTRICAL CHARACTERISTICS (continued)
(AV_DD = DV_DD = 4.75V to 5.25V, external reference V_REF = 4.096V, f_CLK = 3.6MHz (50% duty cycle), T_A = -40°C to +85°C, unless
otherwise noted. Typical values are at AV_DD = DV_DD = 5V, T_A = +25°C. Outputs are unloaded, unless otherwise noted.)
