The device includes a further option that falls between the other two – while it requires less power drawn while
the output drivers are in powerdown, it also takes a slightly longer delay to power-up without artifact than if the
bandgap reference is kept alive. In this alternate mode, the powered-down output driver pin is weakly driven to a
voltage of approximately half the DRVDD1/2 supply level using an internal voltage divider. This voltage will not
match the actual VCM of a fully powered driver, but due to the output voltage being close to its final value, a
much shorter power-up delay time setting can be used and still avoid any audible output artifacts. These output
voltage options are controlled in Page-0/Reg-42.
The high power output drivers can also be programmed to power up first with the output level control in a highly
attenuated state, then the output driver will automatically slowly reduce the output attenuation to reach the
desired output level setting programmed. This capability is enabled by default but can be enabled in
Page-0/Reg-40.
The TLV320AIC3107 includes programmable short-circuit protection for the high power output drivers, for
maximum flexibility in a given application. By default, if these output drivers are shorted, they will automatically
limit the maximum amount of current that can be sourced to or sunk from a load, thereby protecting the device
from an overcurrent condition. In this mode, the user can read Page-0/Reg-95 to determine whether the part is in
short-circuit protection or not, and then decide whether to program the device to power down the output drivers.
However, the device includes further capability to automatically power down an output driver whenever it does
into short-circuit protection, without requiring intervention from the user. In this case, the output driver will stay in
a power down condition until the user specifically programs it to power down and then power back up again, to
clear the short-circuit flag.
The TLV320AIC3107 includes extensive capability to monitor a headphone, microphone, or headset jack,
determine if a plug has been inserted into the jack, and then determine what type of headset/headphone is wired
to the plug. Figure 36 shows one configuration of the device that enables detection and determination of headset
type when a pseudo-differential (capless) stereo headphone output configuration is used. The registers used for
this function are Page-0/Reg 14, 37, 38, and 13. The type of headset detected can be read back from
Page-0/Reg-13. Note that for best results, it is recommended to select a MICBIAS value as high as possible, and
to program the output driver common-mode level at a 1.35V or 1.5V level.

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.
