DG2750
Vishay Siliconix
Low Voltage Dual SPDT Analog Switch with Negative Swing Audio
Capability
DESCRIPTION
The DG2750 is a dual SPDT low on-resistance switch
designed to from a single 1.8 V to 5.0 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+) - 5.0) to V+.
Guaranteed to operate with 1.4 V logic when V+ is in the
range of 2.7 V to 5.0 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 300 mA latch-up protection, as tested
per JESD78.
The DG2750 is assembled in ultra compact mQFN10
package of 1.4 mm x 1.8 mm.
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.
