246 / 252 page  Page 234 21. Electrical Characteristics 21.4 AD Conversion Characteristics TMP86FS23UG 21.4 AD Conversion Characteristics 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 VAREF to 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: ∆VAREF = VAREF − VSS Note 5: The AVDD pin should be fixed on the VDD level even though AD converter is not used. Note 6: When the supply voltage VDD is less than 3.0 V, the operating temperature Topr must be in a range of −20 to 85 °C. (VSS = 0.0 V, 4.5 V ≤ VDD ≤ 5.5 V, Topr = −40 to 85°C) Parameter Symbol Condition Min Typ.
