Note 1: The total error includes all errors except a quantization error, and is defined as a maximum deviation from the ideal con-
version line.
Note 2: Conversion time is different in recommended value by power supply voltage.
About conversion time, please refer to “Register Framing”.
Note 3: Please use input voltage to AIN input Pin in limit of V_AREF – V_SS.
Note 4: Analog Reference Voltage Range: ∆V_AREF = V_AREF − V_SS
Note 5: When AD is used with V_DD < 2.7 V, the guaranteed temperature range varies with the operating voltage.
Note 6: The A_VDD pin should be fixed on the V_DD level even though AD convertor is not used.
