DATASHEET ISL54405 FN6699 Rev 2.00 CD/MP3 Quality Stereo 2:1 Multiplexer with Click and Pop Elimination May 6, 2014 The Intersil ISL54405 is a single supply, bidirectional, dual Features single-pole/double-throw (SPDT) ultra low distortion, high Clickless audio switching OFF-Isolation analog switch that can pass analog signals that are positive and negative with respect to ground. It is primarily 2 switches targeted at consumer and professional audio switching Switch type SPDT or 2 to 1 MUX applications such as computer sound cards and home theater 2V signal switching from 3.3V or 5V supply products. The inputs can accommodate ground referenced RMS signals up to 2V while operating from a single 3.3V or 5V DC RMS -106dB THD+N into 20k load at 2V RMS supply. The digital logic inputs are 1.8V logic-compatible when -108dB THD+N into 32 load at 3.9mW using a single 3.3V or 5V supply. It can be used in both AC or DC coupled ground referenced applications. Signal to noise >124dBV 0.01dB insertion loss at 1kHz, 20k load The ISL54405 features a soft-switch feature and click/pop circuitry at each signal pin that eliminates clicks and pops 0.007dB gain variation 20Hz to 20kHz associated with power-up/down conditions of the preceding 125dB signal muting into 20k load amplifier outputs. 90dB PSRR 20Hz to 20kHz With -106dB THD+N performance with a 2V signal into RMS Single supply operation . 3.3V or 5V 20k load, superior signal muting, high PSRR and very flat frequency response, the ISL54405 meets the exacting Available in 16 Ld TSSOP, 16 Ld TQFN, and 16 Ld TQFN requirements of consumer and professional audio engineers. Pb-Free (RoHS compliant) The ISL54405 is available in 16 Ld TSSOP, 16 Ld 3mmx3mm Applications TQFN, and 16 Ld 2.6mmx1.8mm TQFN packages. Its specified for operation over the -40C to +85C temperature range.
