The NLAS54405 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 referenced signals up to 2 VRMS while operating from a single 3.3 V or 5 V DC supply. The digital logic inputs are 1.8 V logic-compatible when using a single 3.3 V or 5 V supply. It can be used in both AC- or DC-coupled ground-referenced applications. The NLAS54405 has a delayed turn-on 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 . With -117 dB THD+N performance with a 2 VRMS signal into 20 k load, superior signal muting, high PSRR and very flat frequency response, the NLAS54405 meets the exacting requirements of consumer and professional audio engineers.
