Figure 25. TPA0223 Resistor Divider Network Circuit
Using a readily available 1/8-in. (3,5 mm) stereo headphone jack, the control switch is closed when no plug is
inserted. When closed, the 100-k
/1-k divider pulls the ST/MN input low. When a plug is inserted, the 1-k
resistor is disconnected and the ST/MN input is pulled high. The mono speaker is also physically disconnected
from the RO/MO+ output so that no sound is heard from the speaker while the headphones are inserted.
