The DG2517, DG2518 are low-voltage dual single-pole/
double-throw monolithic CMOS analog switches. Designed
to operate from 1.8 V to 5.5 V power supply, the DG2517,
DG2518 achieves a bandwidth of 242 MHz while providing
low on-resistance (3
Ω),
excellent on-resistance matching
(0.2
Ω)
and flatness (1
Ω)
over the entire signal range.
The DG2517, DG2518 offers the advantage of high linearity
that reduces signal distortion, making ideal for audio, video,
and USB signal routing applications. Additionally, the
DG2517, DG2518 are 1.6 V logic compatible within the full
operation voltage range.
Built on Vishay Siliconix’s proprietary sub-micron high-
density process, the DG2517, DG2518 brings low power
consumption at the same time as reduces PCB spacing with
the MSOP10 and DFN10 packages.
As a committed partner to the community and the
environment, Vishay Siliconix manufactures this product
with the lead (Pb)-free device terminations. The DFN
package has a nickel-palladium-gold device termination and
is represented by the lead (Pb)-free "-E4" suffix. The MSOP
package uses 100 % matte Tin device termination and is
represented by the lead (Pb)- free "-E3" suffix. Both the
matte Tin and nickel-palladium-gold device terminations
meet all JEDEC standards for reflow and MSL ratings.
