dg2520 pdf datasheet

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
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.
