DG2520/DG2521 Vishay Siliconix New Product Sub-Ω, Low Voltage, SPDT Analog Switches with Over Current Protection DESCRIPTION FEATURES The DG2520/DG2521 are low-voltage single single-pole/ double-throw monolithic CMOS analog switches. Designed to operate from 1.8 V to 5.5 V power supply, the DG2520/ DG2521 provide low on-resistance (0.8 Ω), excellent onresistance matching (0.06 Ω) and flatness (0.2 Ω) over the entire signal range. • • • • The DG2520/DG2521 offers the advantage of high linearity that reduces signal distortion, making ideal for audio, video, and USB signal routing applications. Additionally, the DG2520/DG2521 are 1.6 V logic compatible within the full operation voltage range. The DG2520/DG2521 offer over current protection. The protection circuitry activates when voltage drop across switch reaches 0.6 V typical. A direct/sustained short circuit will cause the switch to pulse on for typically less than 1 µs, then turn off. The switch turns on after 5 ms. If the short circuit condition remains, the switch turns off and on to produce a pulsed output. The current limiting circuitry is not instantaneous, and therefore will not activate when the output charges a small 0.1 µF capacitor. Built on Vishay Siliconix’s proprietary sub-micron high-density process, the DG2520/DG2521 brings low power consumption at the same time as reduces PCB spacing with the TSOP6 package 1.8 to 5.5 V Single Supply Operation Low Ron: Typical 0.4 Ω at 4.5 V + 1.6 V Logic Compatible Over Current Protection RoHS COMPLIANT BENEFITS • • • • High Linearity Low Power Consumption High Bandwidth Full Rail Signal Swing Range APPLICATIONS • • • • • • • USB/UART Signal Switching Audio/Video Switching Cellular Phone Media Players Modems Hard Drives PCMCIA 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 with 100 % matte tin device termination, the lead (Pb)-free “- E3” suffix is being used as a designator.
