NLAS54404: Ultra-Low THD Stereo SPDT
Switch with Independent
Channel Selects
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 2.3 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.
The NLAS54404 has a soft−switch feature that suppresses clicks
and pops associated with power−up/down conditions of the preceding
amplifier outputs.
With −116 dB THD+N performance with a 2.3 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.
