PRODUCTION DATA
A significant amount of power can be dissipated in the DAC outputs. The device implements a thermal protection circuit that sets the THERM-ALR bit in the status register if the die temperature exceeds +150°C. The THERM-ALR bit can be used in combination with THERM-ALR-CLR (bit 2 in the AUTO-DAC-CLR-SOURCE register) and ACLR-n (bits[14:3] in the AUTO-DAC-CLR-EN register) to set the DAC output to a predefined code when this condition occurs. Note that this feature is disabled when the local temperature sensor powers down.
