SLAS666 – JANUARY 2010
5.2.1.5
Software Power Down
By default, all circuit blocks are powered down following a reset condition. Hardware power up of each
circuit block can be controlled by writing to the appropriate control register. This approach allows the
lowest power-supply current for the functionality required. However, when a block is powered down, all of
the register settings are maintained as long as power is still being applied to the device.
5.2.2
Audio Analog I/O
The TLV320DAC3101 has a stereo audio DAC. It has a wide range of analog interfaces to support
different headsets and analog outputs. The TLV320DAC3101 has features to interface with output drivers
(8-
, 16-, 32-). A special circuit has also been included in the TLV320DAC3101 to insert a short
key-click sound into the stereo audio output. The key-click sound is used to provide feedback to the user
when a particular button is pressed or item is selected. The specific sound of the keyclick can be adjusted
by varying several register bits that control its frequency, duration, and amplitude. See Key-Click
Functionality With Digital Sine-Wave Generator (PRB_P25), Section 5.5.7.
5.3
Digital Processing Low-Power Modes
The TLV320DAC3101 device can be tuned to minimize power dissipation, to maximize performance, or to
an operating point between the two extremes to best fit the application. The choice of processing blocks,
PRB_P1 to PRB_P25 for stereo playback, also influences the power consumption. In fact, the numerous
processing blocks have been implemented to offer a choice among configurations having a different
balance of power optimization and signal-processing capabilities.
