    Note:
    1: power supply is the cathode can't meet the, power supply voltage cannot be more than 5.5 V, the two violation will cause damage of the IC.
    2: with high gain buffer, not any component parameter changes on a board, does not conform to the parameters will lead to damage of the IC.
    3: please try to input line with shielding line, can play a role of anti-interference, eliminate noise currents.
    4: the cmos tube BTL output, around the horn of the cathode can't meet together, namely pick horn line 4 is completely independent, are not allowed to pick up!
