NLAS54405 Datasheet, PDF (1/18 Pages) ON Semiconductor – nLow THD+N Stereo SPDT Switch

NLAS54405
Low THD+N Stereo SPDT
Switch with Click and Pop
Elimination
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 V_RMS 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 V_RMS signal into
20 kW load, superior signal muting, high PSRR and very flat
frequency response, the NLAS54405 meets the exacting requirements
of consumer and professional audio engineers.
