3.3 Thermal Slope

There are three selectable options for the thermal slope: -0.5 dB/°C, -1 dB/°C and -2 dB/°C. This configuration establishes how much attenuation is applied to the signal for each degree Celsius above the temperature threshold.

This control can be adjusted depending on the required attack rate of the application; using the maximum setting allows the device to control its temperature faster when the threshold has been surpassed, however the attenuation will be more perceptible.
