Vishay Intertechnology's DG723 is a monolithic dual single-pull, single-throw analogue switch designed to switch both analogue and digital signals. Delivering low-switching-noise performance for signal integrity and system accuracy, the device combines a compact surface-mount package with low power consumption and can work with low voltages in new-generation portable designs Working from a 1.8 to 5.5V single power supply, the switch 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, analogue front-end gain control, and signal path control circuitry. Applications 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, it provides low on-resistance of 2.5Ω, typical leakage current of 1pA, off capacitance of 8pF, on capacitance of 19pF, and charge injection of 1.8pC. The switch's RON flatness of 0.9Ω at 5V minimises insertion distortion while its low parasitic and charge characteristics help minimise switching noise. The device features a bandwidth of 366MHz at -3dB. It contains two independent SPST switches. Switch 1 is normally open, and switch 2 is normally closed. It is available in lead-free and RoHS-compliant surface-mount TDFN-8 and MSOP-8 packages.
