MUTE FUNCTION
The PGA2320 includes a mute function. This function may
be activated by either the MUTE input (pin 8), or by setting
the gain byte value for one or both channels to 00
HEX
. The
MUTE pin may be used to mute both channels, while the
gain setting may be used to selectively mute the left and
right channels. Muting is accomplished by switching the
input multiplexer to analog ground (AGNDR or AGNDL)
with zero crossing enabled.
The MUTE pin is active low. When MUTE is low, each
channel will be muted following the next zero crossing
event or timeout that occurs on that channel. If MUTE
becomes active while CS is also active, the mute will take
effect once the CS pin goes high. When the MUTE pin is
high, the PGA2320 operates normally, with the mute
function disabled.
This section includes additional information that is
pertinent to designing the PGA2320 into an end
application.
RECOMMENDED CONNECTION DIAGRAM
Figure 5 depicts the recommended connections for the
PGA2320. Power-supply bypass capacitors should be
placed as close to the PGA2320 package as physically
possible.
