Figure 34. Detail of the Volume Control and Mixing Function Shown in Figure 26 and Figure 16
The DAC_L/R signals are the outputs of the stereo audio DAC, which can be steered by register control based
on the requirements of the system. If mixing of the DAC audio with other signals is not required, and the DAC
output is only needed at the stereo line outputs, then it is recommended to use the routing through path
DAC_L3/R3 to the stereo line outputs. This results not only in higher quality output performance, but also in
lower power operation, since the analog volume controls and mixing blocks ahead of these drivers can be
powered down.
If instead the DAC analog output must be routed to multiple output drivers simultaneously (such as to LEFT_LOP
and RIGHT_LOP) or must be mixed with other analog signals, then the DAC outputs should be switched through
the DAC_L1/R1 path. This option provides the maximum flexibility for routing of the DAC analog signals to the
output drivers
The TLV320AIC3107 includes an output level control on each output driver with limited gain adjustment from 0
dB to 9 dB. The output driver circuitry in this device are designed to provide a low distortion output while playing
fullscale stereo DAC signals at a 0dB gain setting. However, a higher amplitude output can be obtained at the
cost of increased signal distortion at the output. This output level control allows the user to make this tradeoff
based on the requirements of the end equipment. Note that this output level control is not intended to be used as
a standard output volume control. It is expected to be used only sparingly for level setting, i.e., adjustment of the
fullscale output range of the device.
Each line output driver can be powered down independently of the others when it is not needed in the system.
When placed into powerdown through register programming, the driver output pins will be placed into a 3-stated,
high-impedance state.
The TLV320AIC3107 includes three high power output drivers with extensive flexibility in their usage. These
output drivers are individually capable of driving 30 mW each into a 16-
load in single-ended configuration, and
two can be connected in bridge-terminated load (BTL) configuration between two driver outputs.
The high power output drivers can be configured in a variety of ways, including:
1. driving one fully differential output signals
2. driving up to three single-ended output signals
3. driving two single-ended output signals, with the remaining driver driving a fixed VCM level, for a
pseudo-differential stereo output
