The DG2537 are low voltage, precision dual SPST switches that can be operated in a single supply or in a dual supply configuration power supply with low power dissipation. The DG2537 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 DG2537 contain two independent Single Pole Single Throw (SPST) switches. Switch-1 and switch-2 are normally open for the DG2537 and normally closed for the DG2538. For the DG2539, switch-1 is normally open and switch-2 is normally closed with a Break-Before-Make switching timing. The DG2537 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.
