BIT 7
BIT 0
BITS 15:6
A left-justified, digital, 10-bit initial DAC value. During a POR these 10 bits are used to fill the
corresponding DAC VALUE register.
BITS 5:2
SEE: These bits have no effect on device operation.
BIT 1
POL: Polarity Select
0 = Normal DAC mode, DAC VALUE = 3FFh results in full-scale output.
1 = Inverted DAC mode, DAC VALUE = 3FFh results in zero output.
BIT 0
EN: LUT Enable
0 = DAC mode: At power-on, the corresponding DAC VALUE register is loaded with the value
stored in the corresponding DAC POR register. Updates from the temperature-referenced LUT
and LUT OFFSET are disabled. The user can write to the DAC VALUE register to set the value for
the DAC. The DAC VALUE register is R/W.
1 = LUT mode: At power-on, the corresponding DAC VALUE register is loaded with the value
stored in the corresponding DAC POR register. After the first valid temperature conversion, the
DAC VALUE register is loaded with the value calculated from the LUT and LUT OFFSET that
correspond to the measured temperature. The DAC VALUE register is read-only.
