JAJSSA9 November 2023 DAC61401 , DAC81401
PRODUCTION DATA
The device incorporates a thermal shutdown that is triggered when the die temperature exceeds 140°C. A thermal shutdown sets the TEMP-ALM bit in the STATUS register, and causes the DAC output to power-down. However, the internal reference remains powered on. The FAULT pin can be configured to monitor a thermal shutdown condition by setting the TEMPALM-EN bit in the SPICONFIG register. After a thermal shutdown is triggered, the device stays in shutdown even after the device temperature lowers.
The die temperature must fall to less than 140°C before the device can be returned to normal operation. To resume normal operation, the thermal alarm must be cleared through the ALM-RESET bit in the TRIGGER register while the DAC channel is in power-down mode.
