Volume control
A digital level control is incorporated in the TDA1306T
which performs the function of soft mute and attenuation
(pseudo-static application mode) or soft mute, attenuation,
fade, increment and decrement (microcontroller
application mode). The volume control of both channels
can be varied in small step changes determined by the
value of the internal fade counter where:
Audio level = counter
× maximum level/120.
Where the counter is a 7-bit binary number between 0 and
120. The time taken for mute to vary from 120 to 0 is
1/120fs. For example, when fs = 44.1 kHz, the time taken
is approximately 3 ms.
VOLUME CONTROL (PSEUDO-STATIC APPLICATION MODE)
In the pseudo-static application mode (APPL = logic 0) the
digital audio output level is controlled by APP0
(attenuation) and APP2 (mute) so only the final volume
levels full scale, 12 dB (attenuate) and mute (
infinity dB)
can be selected. The mute function has priority over the
attenuation function. Accordingly, if MUSB is LOW, the
state of ATSB has no effect. An example of volume control
in this application mode is illustrated in Fig.5.
