Note 1: The total error includes all errors except a quantization error, and is defined as a maximum

deviation from the ideal conversion line.

Note 2: Conversion time is different in recommended value by power supply voltage.

Note 3: Please use input voltage to AIN input pin in limit of VAREF − VSS.

When voltage of range outside is input, conversion value becomes unsettled and gives affect

to other channel conversion value.

Note 4: Analog reference voltage range:

∆V

AREF = VAREF − VSS
