PI3A268C Low-Voltage Dual-SPDT (0.5 ) Analog Switch with Negative Swing Audio Capability Features Description Negative Signal Handling Capability at all Ports PI3A268C is a dual, fast single-pole double throw Low On-Resistance: 0.5 at 3.0V Supply (SPDT) CMOS switch with negative signal handling 0.25 Maximum R Flatness for 3.0V Supply capability at all ports. It can be used as an analog switch ON -3dB Bandwidth: 85MHz or as a low-delay bus switch. Operating over a wide Low-ICCT Current Over an Expanded Control Input power supply voltage ranges from 1.65V to 4.3V, Range PI3A268C processes a low on-resistance and distortion. Wide VDD Range: 1.65V to 4.3V Break-before-make switching prevents both switches Power-off Protection on Common Ports being enabled simultaneously. This eliminates signal Rail-to-Rail Signal Range disruption during switching. High Off Isolation: -80dB 100kHz PI3A268C dissipates a very low supply current even Crosstalk Rejection Reduces Signal Distortion: when the control voltage is lower than supply. This -80dB 100kHz feature suits mobile handset applications by allowing Extended Industrial Temperature Range: 40C to direct interface with the general-purpose I/Os of 85C baseband processors with minimal battery consumption.
