The Intersil ISL54405 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 2VRMS while operating from a single 3.3V or 5V DC
supply. The digital logic inputs are 1.8V logic-compatible when
using a single 3.3V or 5V supply. It can be used in both AC or DC
coupled ground referenced applications. Features The ISL54405 features 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. В±0.01dB insertion loss at 1kHz, 20kпЃ— load With -106dB THD+N performance with a 2VRMS signal into
20kпЃ— load, superior signal muting, high PSRR and very flat
frequency response, the ISL54405 meets the exacting
requirements of consumer and professional audio engineers.
