ISL54406
Stereo Click and Pop Eliminator with Audio Muting
ISL54406
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 TQFN (1.8mmx1.4mm) ultra-thin
package. It operates over a temperature range of -40 to
+85°C.
