CD/MP3 Quality Stereo 2:1 Multiplexer

with Click and Pop Elimination

Features

• Clickless Audio Switching

• 2V Signal Switching from 3.3V or 5V Supply

The Intersil ISL54405 is a single supply, bidirectional, dual

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

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

RMS

• -106dB THD+N into 20kΩ Load @ 2V

RMS

• -108dB THD+N into 32Ω Load @ 3.9mW

• Signal to Noise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . >124dBV

• ±0.01dB Insertion Loss at 1kHz, 20kΩ Load

• ±0.007dB Gain Variation 20Hz to 20kHz

• 125dB Signal Muting into 20kΩ Load

referenced signals up to 2V

while operating from a single

RMS

3.3V or 5V DC 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.

• 90dB PSRR 20Hz to 20kHz

• Single Supply Operation . . . . . . . . . . . . . . . . . . . . 3.3V or 5V

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

• Pb-Free (RoHS Compliant)

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.

Applications

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

RMS

signal into

• Computer Sound Cards

20kΩ load, superior signal muting, high PSRR and very flat

frequency response the ISL54405 meets the exacting

requirements of consumer and professional audio engineers.

• Home Theater Audio Products

• SACD/DVD Audio

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

TQFN, and 16 Ld 2.6mmx1.8mm µTQFN packages. Its

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

range.

• DVD Player Audio Output Switching

• Headsets for MP3/Cellphone Switching

• Hi-Fi Audio Switching Application

For 5V operation connect the 5V_Supply pin to 5V and float the

VDD pin. For 3.3V operation connect the VDD pin to 3.3V and float

the 5V_Supply pin.
