Figure 47. TPA0212 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 SE/BTL input low. When a plug is inserted, the 1-k
resistor is disconnected and the SE/BTL input is pulled high. When the input goes high, the OUT- amplifier is
shut down causing the speaker to mute (virtually open-circuits the speaker). The OUT+ amplifier then drives
through the output capacitor (CO) into the headphone jack.
