6.7.3 Clipping detection
Figure 24. Clipping detection waveforms
Current sinking at pin 10 occurs when a certain distortion level is reached at each output.
This function initiates a gain-compression facility whenever the amplifier is overdriven.
6.7.4 Thermal shutdown
With the thermal shutdown feature, the diagnostics output (pin 10) signals the closeness of
the junction temperature to the shutdown threshold. Typically, current sinking at pin 10 starts
approximately 10° C before the shutdown temperature is reached.
