Stereo Click and Pop Eliminator with Audio Muting

The 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 32 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.

Features

• Single Supply Operation (V ) . . . +2.7V to +5.0V

• Negative Signal Swing Capability. . . . . . . . . .-1.5V

• Low THD

- THD+N at 1mW into 32Load . . . . . . . <0.02%

• Click and Pop Elimination. . . . . . . . . . . . . . >60dB

• Audio Muting . . . . . . . . . . . . . . . . . . . . . >110dB

• Low Power Consumption . . . . 21µW with 3V supply

• Low Power Shutdown Mode

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.

• 1.8V Logic Compatible

• Available in 10 Ld TDFN (3mmx3mm) or tiny

10 Ld (1.8mmx1.4mm) µTQFN Package

• Pb-Free (RoHS Compliant)

Applications

• Consumer Entertainment Systems

• MP3 and other Personal Media Players

• Cellular/Mobile Phones

• PDA’s

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.
