Datasheet
DESCRIPTION
The DG2537, DG2538, and DG2539 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, DG2538 and
DG2539 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
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, DG2538 and DG2539 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.
As a further sign of Vishay Siliconix's commitment, the
DG2537, DG2538 and D2539 are fully RoHS compliant and
halogen-free.
