The Intersil ISL54406 is a Dual SPST (Single Pole/Single
Throw) switch that provides a very low distortion audio path
for a stereo headphone or high impedance line-in load. This
path can be interrupted to provide >110dB of off-isolation for
signal muting purposes into 32Ω or high impedance loads
such as consumer entertainment system line-inputs, MP3
docking systems for powered speaker or automotive
entertainment system in-line or cassette interfaces. Recovery
from muting is instant even with very large DC blocking
capacitors.
The ISL54406 also has comprehensive Click and Pop
elimination measures to prevent these artifacts from occurring
in the load due to system power-up/power-down, codec
enable/disable, headphone hot plug in, and audio muting
on/off situations. The Click and Pop elimination is effective
into low and high impedance loads and requires no external
timing components to deal with DC blocking capacitors placed
between the single supply codec and the load.
The ISL54406 is available in a 10 Ld TDFN (3mmx3mm) or a
tiny 10 Ld μTQFN (1.8mmx1.4mm) ultra-thin package. It
operates over a temperature range of -40 to +85°C.
