A/D Converter Characteristics

A/D Converter characteristics

(VCC = 2.7 to 5.5 V, VSS = 0 V, Ta =

−20 to 85 °C, unless otherwise noted)

A/D Converter Recommended Operating Conditions

(VCC = 2.7 to 5.5 V, VSS = 0 V, Ta =

−20 to 85 °C, unless otherwise noted)

NOTE:

1. When XCIN or the low-speed on-chip oscillator is selected as

φSOURCE, the A/D converter cannot be used.
