·DC Detection Function
This is the function to protect the speaker connected to the digital amplifier output when a DC signal is continuously
output from the digital amplifier.
When MUTEN terminal=L, the DC detection function is disabled.
When a voltage in excess of a given time (tDCDET) and a given level (VDCDET) is output to the digital amplifier output, the
DC detection mode is given. This state outputs an L level signal from PROTN terminal and digital amplifier output
terminals become Weak Low state (a state grounded through a high resistance).
Once the DC detection mode is given, an L level signal keeps outputting from PROTN terminal even if the DC output
state is cancelled. The protection mode is cancelled by turning off the power supply or inputting an L level signal to
SLEEPN terminal momentarily.
And, even if DC protection mode is established by detecting a DC signal, when PROTN terminal is externally connected
to SLEEPN terminal, the protection mode is cancelled and PROTN terminal output is turned from L into Hi-Z state and a
normal operation state is given after a given standby time (tWU).
