M62436FP
Application Example
*
Usage Notes
No measures have been taken to prevent switching noise when the M62436FP’s control switches (SRS on/off, Focus
on/off, and Focus Position H/L) are operated. Therefore several tens of mV of switching noise may be generated. It is
therefore recommended that external muting be applied to the output from the M62436FP when operating the switches.
In addition, it is recommended that external muting be applied at power-on until all the necessary data has been written
by the microprocessor.

The SRS stereo effect can be reduced by connecting resistors (width volume) between pins 5 and 6 and
between pins 33 and 34. However, the resistance value connected between pins 5 and 6 and between pins 33
and 34 should be the same.
