PI3A212S  
Small Plastic Package, Dual SPDT Audio Clickless  
Analog Switch (with Shunt Switches)  
Features  
Description  
• CMOS Technology for Bus and Analog Applications  
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, 2.7Vto 4.2V, the PI3A212S  
has a low On-Resistance of 0.6Ω @ 2.7V.  
• Low On-Resistance: 0.6Ω @ 2.7V  
• Wide V Range: 2.7V TO 4.2V ±10%  
CC  
• Rail-to-Rail Signal Range  
• High Off Isolation: -80dB @ 100 kHz  
Break-before-make switching prevents both switches being en-  
abled simultaneously. This eliminates signal disruption during  
switching.  
• Crosstalk Rejection Reduces Signal Distortion:  
-90dB @ 100 kHz  
• Break-Before-Make 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.  
• Extended Industrial Temperature Range: –40°C to 85°C  
• Packaging: Pb-free & Green, 10-contact TQFN (ZL10)  
Applications  
• Cell Phones  
• PDAs  
• MP3 players
