PT2399 experience

TheBe careful not 9V or 12V as other circuits! circuit is good, and functional, but quiet. Required amplifier circuit. Because the PT2399 is CMOS technology, so it is very sensitive. Be very careful handling your chip, as CMOS devices are prone to being damaged by static electricity. And it is very sensitive to the power supply , it uses the filtered and regulated 5V supply voltage.

Be careful not 9V or 12V as other circuits!
