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
Note 4: Analog Reference Voltage Range: ∆V
