The DG2520 is 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 provide low on-resistance (0.8 O), excellent onresistance matching (0.06 O) and flatness (0.2 O) over the entire signal range.The DG2520 offers the advantage of high linearity that reduces signal distortion, making ideal for audio, video, and USB signal routing applications. Additionally, the DG2520 is 1.6 V logic compatible within the full operation voltage range.The DG2520 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 brings low power consumption at the same time as reduces PCB spacing with the TSOP6 package.
