#161336 - Why does it rise? Responding to: ???'s previous message |
Ap Charles said:
The temperature inside a closed automotive may rise above 85C . But how much of that rise is due to your chip? For a "Mesurement signal conditioning IC", I suspect it's (virtually) none - in which case, how will turning the chip off help? If that's the environment in which your equipment needs to work, then you need to choose parts suitably rated for it! |
