Pinout






Description

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 20k 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 TQFN packages. Its specified for operation over the -40C to +85C temperature range.
