Figure 36. Configuration of device for jack detection using a pseudo-differential (capless) headphone
output connection.
A modified output configuration used when the output drivers are ac-coupled is shown in Figure 37. Note that in
this mode, the device cannot accurately determine the type of headset inserted if a mono or stereo headphone.
Figure 37. Configuration of device for jack detection using an ac-coupled stereo headphone output
connection.
An output configuration for the case of the outputs driving fully differential stereo headphones is shown in
Figure 38. In this mode there is a requirement on the jack side that either HPLCOM or HPLOUT get shorted to
ground if the plug is removed, which can be implemented using a spring terminal in a jack. For this mode to
function properly, short-circuit detection should be enabled and configured to power-down the drivers if a
short-circuit is detected. The registers that control this functionality are in Page-0/Reg-38/Bit-D2-D1.
