Frequently Asked Question
What is the effect of increasing my supply voltage beyond the nominal recommended value?
Increasing the supply voltage (within the functional limits) will increase the current drawn by the part, which means the power dissipation will increase proportional to the square of the voltage. The speed of the digital section of the device will increase slightly, but the data sheet specified performance of the device will be met at the nominal voltage. In any case, thermal dissipation limits for the device must not be exceeded. This means that the junction temperature must not exceed 150°C.
The device should be operated within the nominal voltage plus or minus the specified variance (usually 5%). In all cases the absolute maximum voltage limit must not be approached or exceeded. You will probably blow up your part. Boom!
