LSB
Note1: 1LSB = (DAREFH − DAVSS) / 1024[V]
Note2: The D/A converter must be stopped when operating the TMP1942 with the low-speed clock (fs).
Note3: The supply current flowing through the DAVCC pin is included in the digital supply current
parameter (ICC).
Note4: IDREF electoric current value is an electoric current value when I moved three D/A converter.
