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.
• VDDA = +3.3V ±10%; GNDA = 0V. All voltages with respect to 0V.
• MCLK = 4.096MHz.
