DESCRIPTION

The DG2750 is a dual SPDT low on-resistance switch

designed to from a single 1.6 V to 5.5 V power supply. It is a

bi-directional switch, and is capable of switching negative

swing audio without the need for a coupling capacitor. With

a single power supply, the audio signal can swing over the

range from ((V+) - 5) to V+.

Guaranteed to operate with 1.4 V logic when V+ is in the

range of 2.7 V to 5.5 V, the DG2750 will allow an easy

interface with low voltage DSP or ASIC control logic.

The DG2750 is built on sub micron CMOS low voltage

process technology, has very low quiescent current, and

provides greater than 600 mA latch-up protection, as tested

per JESD78.

The DG2750 is assembled in compact mQFN10,

1.4 mm x 1.8 mm x 0.55 mm and ultra thin UTMQFN of

0.35 mm thickness.

As a committed partner to the community and the

environment, Vishay Siliconix manufactures this product

with lead (Pb)-free device termination. The miniQFN-10

package has a nickel-palladium-gold device termination

and is represented by the lead (Pb)-free “-E4” suffix to the

ordering part number. The nickel-palladium-gold device

terminations meet all JEDEC? standards for reflow and MSL

rating.

As a further sign of Vishay Siliconix’s commitment, the

DG2750 is fully RoHS-complaint and halogen-free.
