DG2535/DG2536 Vishay Siliconix 0.35-Ω Low-Voltage Dual SPDT Analog Switch DESCRIPTION FEATURES The DG2535/DG2536 is a sub 1 Ω (0.35 Ω at 2.7 V) dual SPDT analog switches designed for low voltage applications. The DG2535/DG2536 has on-resistance matching (less than 0.05 Ω at 2.7 V) and flatness (less than 0.2 Ω at 2.7 V) that are guaranteed over the entire voltage range. Additionally, low logic thresholds make the DG2535/DG2536 an ideal interface to low voltage DSP control signals. The DG2535/DG2536 has fast switching speed with break-before-make guaranteed. In the On condition, all switching elements conduct equally in both directions. Off-isolation and crosstalk is - 69 dB at 100 kHz. The DG2535/DG2536 is built on Vishay Siliconix’s high-density low voltage CMOS process. An eptiaxial layer is built in to prevent latchup. The DG2535/DG2536 contains the additional benefit of 2,000 V ESD protection. In space saving MSOP-10 and DFN-10 lead (Pb)-free packages, the DG2535/DG2536 are high performance, low rON switches for battery powered applications. No lead (Pb) is used in the manufacturing process either inside the device/ package or on the external terminations. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured in DFN packages, the lead (Pb)-free "-E3/E4" suffix is being used as a designator. Lead (Pb)-free DFN products purchased at any time will have either a nickel-palladium-gold device termination or a 100 % matte tin device termination. The different lead (Pb)-free materials are interchangeable and meet all JEDEC standards for reflow and MSL rating. • • • • • • Low Voltage Operation Low On-Resistance - rON: 0.35 Ω at 2.7 V - 69 dB OIRR at 2.7 V, 100 kHz MSOP-10 and DFN-10 Packages ESD Protection > 2000 V Latch-Up Current > 300 mA (JESD 78) RoHS COMPLIANT BENEFITS • • • • • Reduced Power Consumption High Accuracy Reduce Board Space 1.8 V Logic Compatible High Bandwidth APPLICATIONS • • • • • • Cellular Phones Speaker Headset Switching Audio and Video Signal Routing PCMCIA Cards Battery Operated Systems Relay Replacement FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG2535 V+ 1 10 NO2 NO1 2 9 COM2 Logic NC1 and NC2 NO1 and NO2 COM1 3 8 IN2 0 ON OFF IN1 4 7 NC2 1 OFF ON NC1 5 6 GND Top View TRUTH TABLE ORDERING INFORMATION DG2536 Temp Range V+ NC1 1 10 NC2 2 9 COM2 COM1 3 8 IN2 IN1 4 7 NO2 NO1 5 6 GND Document Number: 72939 S-71009-Rev.
