| DG2015 New Product Vishay Siliconix Low-Voltage, Low rON, Dual DPDT Analog Switch FEATURES D D D D Low Voltage Operation (2.7 V to 3.3 V) Low On-Resistance - rON: 0.85 W 3 dB Loss @ 100 MHz Fast Switching: tON = 40 ns tOFF = 35 ns D QFN-16 Package BENEFITS D D D D D Reduced Power Consumption High Accuracy Reduce Board Space TTL/1.8-V Logic Compatible High Bandwidth APPLICATIONS D D D D D Cellular Phones Speaker Headset Switching Audio and Video Signal Routing PCMCIA Cards Battery Operated Systems DESCRIPTION The DG2015 is a dual double-pole/double-throw monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, high speed, low on-resistance and small physical size, the DG2015 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2015 is built on Vishay Siliconix's low voltage JI2 process. An epitaxial layer prevents latchup. Break-before-make is guaranteed. The switch conducts equally well in both directions when on, and blocks up to the power supply level when off.

Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum current ratings. b. All leads welded or soldered to PC Board. c. Derate 23.5 mW/_C above 70_C d. Manual soldering with iron is not recommended for leadless components. The QFN is a leadless package. The end of the lead terminal is exposed copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper lip cannot be guaranteed and is not required to ensure adequate bottom side solder interconnection.
