| DG2032 New Product Vishay Siliconix High-Bandwidth, Low Voltage, Dual SPDT Analog Switch FEATURES D Single Supply (1.8 V to 5.5 V) D Low On-Resistance - rON: 2.4 W D Crosstalk and Off Isolation: -81 dB @ 1 MHz D QFN-12 (3 x 3 mm) Package BENEFITS D D D D D Reduced Power Consumption High Accuracy Reduce Board Space Low-Voltage Logic Compatible High Bandwidth APPLICATIONS D D D D D D Cellular Phones Speaker Headset Switching Audio and Video Signal Routing PCMCIA Cards Low-Voltage Data Acquisition ATE DESCRIPTION The DG2032 is a monolithic CMOS dual single-pole/ double-throw (SPDT) analog switch. It is specifically designed for low-voltage, high bandwidth applications. The DG2032's on-resistance (3 W @ 2.7 V), matching and flatness are guaranteed over the entire analog voltage range. Wide dynamic performance is achieved with better than -80 dB for both cross-talk and off-isolation at 1 MHz. Both SPDT's operate with independent control logic, conduct equally well in both directions and block signals up to the power supply guaranteed. level when off. Break-before-make is With fast switching speeds, low on-resistance, high bandwidth, and low charge injection, the DG2032 is ideally suited for audio and video switching with high linearity. Built on Vishay Siliconix's low voltage CMOS technology, the DG2032 contains an epitaxial layer which prevents latch-up.

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 16.2 mW/_C above 70_C d. Manual soldering with an 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.
