3. CHARACTERISTICS & SPECIFICATIONS
RECOMMENDED OPERATING CONDITIONS
ANALOG CHARACTERISTICS
•
Min / Max characteristics and specifications are guaranteed over all
Recommended Operating Conditions
•
Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
•
VA+ = VD+ = 5 V ±5%; AGND = DGND = 0 V; VREFIN = +2.5 V. All voltages with respect to 0 V.
•
MCLK = 4.096 MHz.
