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 HPCOM 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.
