CD/MP3 Quality Stereo 2:1 Multiplexer with Click and Pop Elimination

The Intersil ISL54405 is a single supply, bidirectional, dual

Features

single-pole/double-throw (SPDT) ultra low distortion, high

• Clickless audio switching

• 2 switches

• Switch type SPDT or 2 to 1 MUX

• 2V signal switching from 3.3V or 5V supply

OFF-Isolation analog switch that can pass analog signals that

are positive and negative with respect to ground. It is primarily

targeted at consumer and professional audio switching

applications such as computer sound cards and home theater

products. The inputs can accommodate ground referenced

RMS

• -106dB THD+N into 20k load at 2V

signals up to 2V

while operating from a single 3.3V or 5V DC

RMS

supply. The digital logic inputs are 1.8V logic-compatible when

using a single 3.3V or 5V supply. It can be used in both AC or DC

coupled ground referenced applications.

• -108dB THD+N into 32 load at 3.9mW

• Signal to noise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . >124dBV

• ±0.01dB insertion loss at 1kHz, 20k load

• ±0.007dB gain variation 20Hz to 20kHz

• 125dB signal muting into 20k load

The ISL54405 features a soft-switch feature and click/pop

circuitry at each signal pin that eliminates clicks and pops

associated with power-up/down conditions of the preceding

amplifier outputs.

• 90dB PSRR 20Hz to 20kHz

With -106dB THD+N performance with a 2V

signal into

• Single supply operation . . . . . . . . . . . . . . . . . . . . . . . . . 3.3V or 5V

• Available in 16 Ld TSSOP, 16 Ld TQFN, and 16 Ld µTQFN

• Pb-Free (RoHS compliant)

20k load, superior signal muting, high PSRR and very flat

frequency response, the ISL54405 meets the exacting

requirements of consumer and professional audio engineers.

The ISL54405 is available in 16 Ld TSSOP, 16 Ld 3mmx3mm

TQFN, and 16 Ld 2.6mmx1.8mm µTQFN packages. It’s specified

for operation over the -40°C to +85°C temperature range.

Applications

• Computer sound cards

• Home theater audio products

• SACD/DVD audio
