NLAS54405 Low THD+N Stereo SPDT Switch with Click and Pop Elimination The NLAS54405 is a single supply, bidirectional, dual singlepole / doublethrow (SPDT) ultra-low distortion, high OFFIsolation www.onsemi.com 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 V while operating from a single 3.3 V or RMS 1 5 V DC supply. The digital logic inputs are 1.8 V logiccompatible WQFN16 when using a single 3.3 V or 5 V supply. It can be used in both AC or MT SUFFIX DCcoupled ground-referenced applications. CASE 488AP The NLAS54405 has a delayed turnon feature and click/pop circuitry at each signal pin that eliminates clicks and pops associated with powerup/down conditions of the preceding amplifier outputs. MARKING DIAGRAM With 117 dB THD+N performance with a 2 V signal into RMS 20 k load, superior signal muting, high PSRR and very flat frequency response, the NLAS54405 meets the exacting requirements AH M of consumer and professional audio engineers.
