Rev 1.00
January 14, 2010 Audio/USB 2.0 Wired-OR Switch with Click and Pop Reduction
The Intersil ISL54409 and ISL54410 are Dual SPST
(Single Pole/Single Throw) switches that provide a
very low distortion audio path for a stereo headphone
and can be connected in a wired-OR configuration at
the switch outputs with USB2.0 HS signals for
Audio/USB signal multiplexing to a common
connector. The audio switch path can be disabled to
provide high signal isolation, preventing crosstalk
between the audio codec and USB data signals. Features The ISL54409 and ISL54410 analog switches are
negative swing capable with a single supply voltage
and maintain excellent THD performance within a
signal range of -1V to +1V. The switch terminals have
low pin capacitance (4pF typical), minimizing impact
to USB 2.0 High-Speed signals. The ISL54409 offers a
Low Power Shutdown mode while the ISL54410 offers
a High Off-Isolation mode. The ISL54410 contains
active Audio Click and Pop Elimination circuitry for ACcoupled audio signals. Audio Muting . >110dB The ISL54409 and ISL54410 are available in a 8 Ld
TDFN (2mmx2mm) or a 10 Ld ВµTQFN
(1.8mmx1.4mm) package. They operate over a …
