Applications
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, PI3A288
processes a low on-resistance and distortion. The ultra-
low THD performance enables PI3A288 to apply in
high-quality audio applications.
PI3A288 has also a soft-start and soft-stop feature so as
to minimize signal disruption during channel switching
