MUTE FUNCTION
Muting can be achieved by either hardware or software
control. Hardware muting is accomplished via the
MUTE input, and software muting by loading all zeroes
into the volume control register.
MUTE disconnects the internal buffer amplifiers from
the output pins and terminates A
OUT
L and A
OUT
R with
10k
resistors to ground. The mute is activated with a
zero crossing detection (independent of the zero cross
enable status) or an 16ms time-out to eliminate any au-
dible
clicks
or
pops
. MUTE also initiates an internal
offset calibration.
A software mute is implemented by loading all zeroes
into the volume control register. The internal amplifier
is set to unity gain with the amplifier input connected to
AGND.
RECOMMENDED CONNECTION DIAGRAM
Figure 5 depicts the recommended connections for the
PGA2311. Power-supply bypass capacitors should be
placed as close to the PGA2311 package as physically
possible.
