Total error
Note 1: The total error includes all errors except a quanitization error, and is defined as a maximum deviation from the ideal con-
version line.
Note 2: Conversion time is defferent in recommended value by power supply voltage.
Note 3: The voltage to be input on the AIN input pin must not exceed the range between V
range is input, conversion values will become unstable and conversion values of other channels will also be affected.
Note 4: Analog reference voltage range: ∆V
Note 5: When AD converter is not used, fix the AVDD and VAREF pin on the V
