Note 1: The total error includes all errors except a quantization error, and is defined as the maximum deviation from the ideal con-
Note 2: Conversion times differ with variation in the power supply voltage.
Note 3: The voltage to be input to the AIN input pin must be within the range V
Note 4: If the AD converter is not used, fix the V
