Stereo Click and Pop Eliminator with Audio Muting

ISL54406

Features

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

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

• Low THD

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.

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

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

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

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

• Low Power Shutdown Mode

• 1.8V Logic Compatible

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.

• 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.
