Hi team,
I am in need to monitor actuator positions through the use of LVDT interfaces in an avionics application.
I have looked into the PGA970 as a potential ‘one stop shop’ for a device that would deal with these LVDT interface needs.
1. Do you happen to know of any use of this device in a similar application that already gained some level of design pedigree?
2. Can you confirm that this part is currently being used elsewhere within flight safety critical application (i.e. to DO-254 DAL-A)?
3. If you can provide confirmation to question 2 above, what is the standpoint regarding DAL-A certification?
As the device contains an integrated ARM core, there is the potential that this device would be classified as ‘complex’.
If this were to be the case, we would need a cert pack from yourselves (TI) in order to justify the use of the part.
This justification would not be required however if it can be proven that the device is fully analysable and testable.
