APPLICATION METHOD FOR M52742SP
CLAMP PULSE INPUT
Clamp pulse width is recommended
above 15kHz, 1.0
μ

above 30kHz, 0.5
μ

above 64kHz, 0.3
μ
sec.
The clamp pulse circuit in ordinary set is a long round about way,
and beside high voltage, sometimes connected to external terminal,
it is very easy affected by large surge.
Therefore, the Fig. shown right is recommended.
EXT-FEED BACK
In case of application circuit example of lower figure, Set up R1, R2
which seems that the black level of the signal feedbacked from
Power AMP is 1V, when the bottom of output signal is 1V.
NOTICE OF APPLICATION
Make the nearest distance between output pin and pull down
resister.
Recommended pedestal voltage of IC output signal is 2V.
