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.
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.
With -106dB THD+N performance with a 2VRMS signal into
20kΩ load, superior signal muting, high PSRR and very flat
frequency response the ISL54405 meets the exacting
requirements of consumer and professional audio engineers.
The ISL54405 is available in 16 Ld TSSOP, 16 Ld 3mmx3mm
TQFN, and 16 Ld 2.6mmx1.8mm μTQFN packages. Its
specified for operation over the -40°C to +85°C temperature
range.
