Output low-pass filter
To avoid EMI problems, it may be necessary to use a low-pass filter before the speaker. The
cutoff frequency should be larger than 22 kHz and much lower than the output switching
frequency. It is necessary to choose the L-C component values depending on the loud
speaker impedance. Some typical values, which give a cut-off frequency of 27 kHz, are

Protection function
The TDA7492MV is fully protected against overvoltages, undervoltages, overcurrents and
thermal overloads as explained here.
Overvoltage protection (OVP)
page 8 the overvoltage protection is activated which forces the outputs to the
high-impedance state. When the supply voltage falls back to within the operating range the
device restarts.
Undervoltage protection (UVP)
specifications on page 8 the undervoltage protection is activated which forces the outputs to
