Notes
4. The speakers must both be connected with the plus (+) side closest to the IC.
5. Oscillations may appear in the output waveform under conditions that depend on the IC operating conditions and the
connected load. If this problem occurs, the oscillation stability can be improved by inserting 0.047
F capacitors (use
capacitors with a low variation in capacitance with temperature) and 4.7
resistors in series in the two positions
shown in dotted lines in figure 3. Verify the quality of the output waveform in an actual end product.
6. Pin 19 must not be connected to any signal; it must be left open. (This is because it is connected inside the chip.)
