The Intersil ISL54405 is a single supply, bi-directional, dual single-pole/double-throw (SPDT) analogue switch featuring ultra low distortion and off-isolation capabilities into all load types. It is designed to pass analogue signals that are positive and negative with respect to ground, with inputs that accommodate ground referenced signals up to 2VRMS, while operating from a single 3.3V or 5V DC supply. Targeted for consumer and professional audio switching applications, the switch saves costs by eliminating the negative supply and associated components typically used for amplifier output signal muting. It also consumes minimal power, reducing the size and heat typical of traditional designs. The switch is for computer sound cards and audio products such as CD/SACD/DVD-Audio Players, DVD players and Blu-ray devices. It can also be used in high-end audio equipment and audio docking accessories. By exceeding CD/MP3 quality audio specifications, it lets users raise their end-product specifications. Digital logic inputs are 1.8V logic-compatible when using a single 3.3V or 5V supply. Designed for both AC or DC coupled ground-referenced applications, the switch also features a programmable soft-switch feature and click/pop circuitry at each signal pin to eliminate the clicks and pops associated with power-up/down and channel switching events.
