Application information
27/32
With the values above, the result is FCL=25Hz.
In this case,
τ in = Rin xCin=6.6ms.
This value is sufficient with regard to the previous formula, thus we can state that the pop is
imperceptible.
Connecting the headphones
Generally headphones are connected using jack connectors. To prevent a pop in the
headphones when plugging in the jack, a pulldown resistor should be connected in parallel
with each headphone output. This allows the capacitors Cout to be charged even when the
headphones are not plugged in.
Pulldown resistors with a value of 1 k
Ω are high enough to be a negligible load, and low
enough to charge the capacitors Cout in less than one second.
Note:
The pop&click reduction circuitry works properly only when both channels have the same
value for the external components Cin, Cout, Rload and Rpulldown.
