Temperature Protection
TEMPERATURE PROTECTION IS NOT AVAILABLE FOR DEFAULT FIRMWARE RELEASES < 4.5_0.3 (REFER TO § 13)
To preserve hardware damages, DT5730 and DT5725 implement an automatic turning off of the board channels in
event of internal over-temperature. Internal temperature can be monitored through register address 0x1nA8.
The over-temperature limit is fixed at 70°C. As soon as the internal temperature exceeds 70°C, the board enters the
temperature protection condition and the firmware automatically performs the following actions:
•
turns off all the channel ADCs;
•
stops the acquisition, if running (data possibly stored at that moment can be readout in any case).
This status is valid as long as the internal temperature remains over 62°C. Starting from 61°C, the user is allowed to
turn on the channel ADCs again and restart the acquisition, if necessary.
The temperature protection can be controlled through register addresses 0x8104 and 0x81C0.
