Reference, Voltage Monitors, and Temp Sensor
ELECTRICAL CHARACTERISTICS (continued)
(DVDD = 1.8V to 3.6V, AVDD = 2.7V to 5.5V, VREFDAC = VREFADC = 2.5V, external reference; 10µF capacitor at REFADC and REFDAC;
0.01µF capacitor at REFADJ; TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
