Popless Implementation on the NLAS6233
Audio sources such as amplifiers or CODECs can generate
undesirable, transient voltage spikes when powering up and
down. Those voltage spikes can be translated into current
surges and ultimately lead to audible pop noises in the speaker
if not diverted or suppressed. The NLAS6233 includes
popless noise suppression circuitry designed to prevent such
undesirable pops from propagating through to the speaker.
This feature is realized through a deliberate increase in the
Break-Before-Make time, tBBM, and is useful in applications
where a switch is used to alternate between two different
audio sources.
When the signal from the common pin is removed from
one terminal, the switch waits an extended amount of time
before connecting to the opposite terminal. The time interval
for tBBM is a function of the supply voltage of the switch,
VCC. Figure 14 shows the relationship of tBBM for each VCC
value within the recommended operating voltage range.
