PI3A212S Small Plastic Package, Dual SPDT Audio Clickless Analog Switch (with Shunt Switches) Features * * * * * * CMOS Technology for Bus and Analog Applications Low On-Resistance: 0.6 @ 2.7V Wide VCC Range: 2.7V TO 4.2V 10% Rail-to-Rail Signal Range High Off Isolation: -80dB @ 100 kHz Crosstalk Rejection Reduces Signal Distortion: -90dB @ 100 kHz * Break-Before-Make Switching * Extended Industrial Temperature Range: -40C to 85C * Packaging: Pb-free & Green, 10-contact TQFN (ZL10) Description Pericom Semiconductor's PI3A212S is a dual high-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 enabled 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.
