Electrical Characteristics 25.4 AD Conversion Characteristics TMP89FS60 RA003 25.4 AD Conversion Characteristics Note 1: The total error includes all errors except a quantization error, and is defined as the maximum deviation from the ideal con- version line. 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 VAREF to VSS. If a voltage outside this range is input, converted values will become indeterminate, and converted values of other channels will be affected. Note 4: Analog reference voltage range: ∆V AREF = VAREF − VSS Note 5: If the AD converter is not used, fix the AVDD and VAREF pin to the VDD level.
