Manufacturer Part Number
isl54213
Description
Mp3/usb 2.0 High Speed Switch With Negative Signal Handling And Mute Function
Manufacturer
Intersil Corporation
Datasheet
MP3/USB 2.0 High Speed Switch with
Negative Signal Handling and Mute
Function
The Intersil ISL54213 dual SPDT (Single Pole/Double Throw)
switch combines low distortion audio and accurate USB 2.0
high speed data (480Mbps) signal switching in the same low
voltage device. When operated with a 2.5V to 5.0V single
supply, this analog switch allows 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 ISL54213 logic control pins are 1.8V compatible, which
allows for control via a standard µcontroller.
The part has an audio enable control pin to open all switches
and put the part in a mute state. It’s high off-isolation
(95dB @ 100kHz) provides superior muting of audio signals.
The ISL54213 is available in a small 10 Ld 2.1mmx1.6mm
ultra-thin µTQFN package and a 10 Ld 3mmx3mm TDFN
package. It operates over a temperature range of -40°C to
+85°C.
