PI5A4764 Small Package, Dual SPDT Audio Clickless Analog Switch Features Description • • • • • • • • • • • Pericom Semiconductor's PI5A4764 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, 1.65V to 5.5V, the PI5A4764 has a low On-Resistance of 0.6Ω @ 2.7V. CMOS Technology for Bus and Analog Applications Low On-Resistance: 0.6Ω @ 2.7V Wide VCC Range: 1.65V TO 5.5V Rail-to-Rail Signal Range Control Input Overvoltage Tolerance: 5.5V min. High Off Isolation: -53dB Crosstalk Rejection Reduces Signal Distortion: -84dB Break-Before-Make Switching Low THD (0.017% @ VCC = 2.7V) Extended Industrial Temperature Range: –40°C to 85°C Packaging (Pb-free & Green): - 10-ball CSP Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, INX, tolerates input drive signals up to 6.0V, independent of supply voltage. The PI5A4764 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.
