The NLAS54404 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 2.0 VRMS while operating from a single 3.3 V DC supply. The digital logic inputs are 1.8 V logic-compatible. It is used in DC-coupled ground-referenced applications. With -118 dB THD+N performance with a 2.0 VRMS signal into 20 k load, superior signal muting, high PSRR and very flat frequency response, the NLAS54404 meets the exacting requirements of consumer and professional audio engineers.
