MEMORY TYPE
The M4DAC LUT is set of registers assigned to hold the voltage profile for the M4DAC. The values in this table
determine the set point for the M4DAC. The MON4 voltage measurement is used to index the LUT (VINDEX,
Table 02h, Register 84h), starting at Register 80h in Table 06h. Values recalled from this EEPROM memory
table are written into the M4DAC (Table 02h, Register 85h) location that holds the value until the next MON4
voltage conversion. The DS1875 can be placed into a manual mode (M4DAC EN bit, Table 02h, Register 80h),
where M4DAC is directly controlled for calibration. If voltage compensation is not required by the application,
program the entire LUT to the desired M4DAC set point.
