The DG721, DG722 and DG723 are precision dual SPST switches designed to operate from single 1.8 V to 5.5 V power supply with low power dissipation. The DG721, DG722 and DG723 can switch both analog and digital signals within the power supply rail, and conduct well in both directions. Fabricated with advance submicron CMOS process, these switches provide high precision low and flat ON resistance, low leakage current, low parasitic capacitance, and low charge injection. The DG721, DG722 and DG723 contain two independent Single Pole Single Throw (SPST) switches. Switch-1 and switch-2 are normally open for the DG721 and normally closed for the DG722. For the DG723, switch-1 is normally open and switch-2 is normally closed with a Break-BeforeMake switching timing. The DG721, DG722 and DG723 are the ideal switches for use in low voltage instruments and healthcare devices, fitting the circuits of low voltage ADC and DAC, analog front end gain control, and signal path control. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with lead (Pb)-free device termination. The TDFN8 package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free “-E4” suffix to the ordering part number. The MSOP-8 package has tin device termination and is represented by “-E3”. Both device terminations meet all JEDEC standards for reflow and MSL rating. As a further sign of Vishay Siliconix"s commitment, the DG721, DG722 and D723 are fully RoHS compliant and Halogen-free.
