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-Before-
Make 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.

Notes:
a. Room = 25 °C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, nor subjected to production test.
e. V
IN
= input voltage to perform proper function.
f. Not production tested.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
