PI3A212S
Small Plastic Package, Dual SPDT Audio Clickless
Analog Switch (with Shunt Switches)
Description
PericomSemiconductor'sPI3A212Sisadualhigh-bandwidth,fast
single-pole double throw (SPDT) CMOS switch. It can be used as
an analog switch or as a low-delay bus switch. Specified over a
wide operating power supply voltage, 2.7V to 4.2V, the PI3A212S
has a low On-Resistance of 0.6 @ 2.7V.
Break-before-make switching prevents both switches being en-
abled simultaneously. This eliminates signal disruption during
switching.
The PI3A212S shunt switches connected to ground in order to
dissipate capacitance that builds up on the unconnected NC or
NO line. As a result, reduction of popping and clicking sounds is
achieved when switching between audio sources.
