Suppression
The Intersil ISL54211 dual SPDT (Single Pole/Double Throw)
switches combine low distortion audio and accurate USB 2.0
high speed data (480Mbps) signal switching in the same low
voltage device. When operated with a 2.7V to 5.0V single
supply these analog switches allow audio signal swings
below-ground, allowing the use of a common USB and audio
headphone connector in Personal Media Players and other
portable battery powered devices.
The ISL54211 logic control pins are 1.8V compatible with a
supply voltage of 2.7V to 3.6V, which allows for control via a
standard µcontroller.
The part has an audio enable control pin (CTRL) to open all
in-line switches and activate the audio click and pop circuitry.
The high OFF-isolation and special click/pop circuitry of the
audio switches eliminates click and pops in the head-phones
when the audio CODEC drivers are powering up or down or
when a headphone is inserted or removed from the
headphone jack.
It’s available in a tiny 10 Ld 1.8mmx1.4mm ultra-thin µTQFN
package and a 10 Ld 3mmx3mm TDFN package. It operates
over a temperature range of -40 to +85°C.
