NLAS54405数据手册集成电路（IC）的模拟开关多路复用器解复用器规格书PDF

描述 Description

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 2.3 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 soft−switch 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 −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 NLAS54405 meets the exacting requirements
of consumer and professional audio engineers.
