PI3A288

Product Description

The PI3A288 is a dual, single-pole double throw (SPDT) CMOS switch with negative signal handling capability at all ports. It can be used as an analog switch or as a low-delay bus switch. Operating over a wide power supply voltage ranges from 1.65V to 4.3V, the PI3A288 processes a low on-resistance and distortion. The ultralow THD performance enables the PI3A288 to apply in high-quality audio applications. The PI3A288 has also a soft-start and soft-stop feature so as to minimize signal disruption during channel switching
