DESCRIPTION

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

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.
