Dual SPST Analog Switch handles analog and digital signals.December 10, 2010 -
Operating from 1.8-5.5 V single power supply, Model DG723 contains 2 independent SPST switches, one normally open and one normally closed. Monolithic device provides low typical on-resistance of 2.5 W, typical leakage current of 1 pA, off capacitance of 8 pF, and on capacitance of 19 pF. With typical bandwidth of 366 MHz at -3 dB, RoHS-compliant switch is suited for low-voltage instruments, healthcare devices, portable meters, PDAs, and modems.

New Vishay Siliconix Dual SPST Analog Switch
Features 1.8 V to 5.5 V Single Power Supply and 2.5W On-Resistance in Surface-Mount MSOP-8 Package
MALVERN, PENNSYLVANIA - Vishay Intertechnology, Inc. (NYSE: VSH) today released the DG723, a monolithic dual single-pull, single-throw analog switch designed to switch both analog and digital signals. Delivering low-switching-noise performance for signal integrity and system accuracy, the new device combines a compact surface-mount package with low power consumption and the ability to work with the low voltages in new-generation portable designs.
Working from a 1.8 V to 5.5 V single power supply, the DG723 is intended for end products including low-voltage instruments, healthcare devices, portable meters, PDAs, and modems, where it will be used in conjunction with ADC, DAC, analog front end gain control, and signal path control circuitry. Typical applications will include programmable gain control, active filtering, sample-and-hold, audio/video and digital signal switching and routing, and reed relay replacement.
Fabricated with advanced submicron CMOS technology, the DG723 provides low typical on-resistance of 2.5W, typical leakage current of 1 pA, off capacitance of 8 pF, on capacitance of 19 pF, and charge injection of 1.8 pC. The switch's RON flatness of 0.9W at 5 V minimizes insertion distortion while its low parasitic and charge characteristics help to minimize switching noise. The device features typical bandwidth of 366 MHz at − 3 dB.
The DG723 contains two independent SPST switches. Switch 1 is normally open and Switch 2 is normally closed.
Offered in the lead (Pb)-free and RoHS compliant surface-mount TDFN-8 and MSOP-8 packages, samples and production quantities of the DG723 are available now with lead times of 8 to 10 weeks for large orders.
