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 T
A
= 25°C.
• VDDA = +3.3V ±10%; GNDA = GNDD = 0V. All voltages with respect to 0V.
• MCLK = 4.096MHz.
