18.5 ADC Electrical Characteristics
Analog reference voltage (+)
Analog reference voltage (–)
Analog input voltage
Analog supply current
Total error (not including quantization error)
Note 1: 1 LSB = (VREFH – VREFL) / 1024 (V)
Note 2: The A/D converter must be stopped when operating the TMP1940CYAF with the low-speed clock (fs).
Note 3: The supply current flowing through the AVCC pin is included in the digital supply current parameter (ICC).
