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.
