| DG2017 New Product Vishay Siliconix Low-Voltage, Low rON, Dual DPDT Analog Switch FEATURES D Low Voltage Operation (2.0 V to 5.5 V) D Low On-Resistance @ 2.7 V - rON: SW1, SW2 - 3.2 W SW3, SW4 - 0.64 W D Fast Switching: tON = 46 ns tOFF = 21 ns D QFN-16 (4x4 mm) Package BENEFITS D D D D Space Saving Solution Low Power Consumption Guaranteed Low Voltage Operation Low Voltage Logic Compatible APPLICATIONS D D D D D Cellular Phones Integrated Speaker Switching Audio and Video Signal Routing PCMCIA Cards Battery Operated Systems DESCRIPTION The DG2017 is a dual DPDT (double-pole/double-throw), optimized for high performance analog switching, and specifically designed to benefit portable audio applications. One pair of double-throw switches is sub 1 W for low impedance speaker performance while the second pair of double-throw switches is suitable for microphone applications. With the DPDT configuration, the DG2017 provides the flexibility for stereo-single-end or differential BTL output structures with a fully integrated differential microphone switching solution. The DG2017 is an integrated monolithic device in a QFN-16 (4 x 4 mm) package that provides a space saving solution over the use of multiple single SPDT devices as well as providing the advantage of on-resistance flatness and matching that single SPDT devices cannot offer. The DG2017 provides low charge injection (2 pC), fast switching time (tON and tOFF less than 100 ns), excellent Off-Isolation and Crosstalk (-70 dB @ 100 kHz). During operation, continuous current through any or all switches is rated at "200 mA, ideal for portable audio applications. Built on Vishay Siliconix's low voltage CMOS process, the DG2017 contains an epitaxial layer that prevents latchup. Break-before-make is guaranteed. When on, each switch conducts equally well in both directions, and block up to the power supply level when off.

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.
