The DG722 are precision dual SPST switches designed to operate from single 1.8 V to 5.5 V power supply with low power dissipation. The DG722 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 DG722 contain two independent Single Pole Single Throw (SPST) switches. Switch-1 and switch-2 are normally closed for the DG722. The DG722 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.
