Low-voltage analog switch family targets portable systems

Malvern, Pa. — Vishay Intertechnology, Inc. today released a family of low on-resistance and low-level logic control analog switches designed for direct battery operation in portable applications.

Offering low on-resistance R(ON) and low-level logic control through the full voltage range of 1.6 V to 4.3 V, the switches are aimed at cell phones, set-top boxes, PDAs, and media players.

Low-level logic control is guaranteed throughout the voltage supply range. For example, the DG2799 double-pole, double throw (dpdt) analog switch guarantees 1.6-V logic at a 4.3-V power supply. The device features low R(ON) of 0.25Ω typical at 2.7 V and switching times of 57 ns (ON) and 45 ns (OFF). It is packaged in a QFN-16 (3mm x 3mm) package.

The DG2714 is a break-before-make single-pole, double throw (spdt) monolithic CMOS analog switch that combines low-voltage operation from 1.6 V to 3.6 V, switching times of 51 ns (ON) and 33 ns (OFF), and R(ON) of 0.85Ω typical in a SC-70 package.

The DG2715 and DG2716 are bidirectional single-pole, single throw (spst)
switches that feature low-voltage operation from a single 1.65 V to 3.6 V
supply, fast switching speeds of 29 ns (ON) and 26 ns (OFF), and low
R(ON) values of 0.4Ω typical at 2.7 V and 1.5Ω at 1.8 V.
These two spst switches, available in the SC-70 package, also offer
R(ON) flatness of 0.2Ω.

Also released today, the DG2741, DG2742, and DG2743 are low-voltage,
single-supply, dual spst switches with R(ON) values down to
0.4Ω typical at 2.7 V, fast switching speeds of 30 ns (ON) and 28 ns
(OFF), and the ability to handle signals over the entire analog voltage
range. On-resistance flatness and matching of 0.18Ω and 0.08Ω,
respectively, ensure high accuracy between channels. The DG274x switches
come in SOT23-8 and MSOP-8 packages.
