DG2750 Vishay Siliconix Low Voltage Dual SPDT Analog Switch with Negative Swing Audio Capability DESCRIPTION FEATURES 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. • Capable to switch negative swing audio without dc blocking capacitor • Low on-resistance • 1.4 V high logic • Latch-up current > 300 mA (JESD78) • Reduced power consumption • Reduce board space • Compliant to RoHS directive 2002/95/EC APPLICATIONS • Cellular phones • Portable media players • Computer and game machine • Handheld healthcare and instruments FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION NC2 GND miniQFN-10L 7 6 IN2 1 28 9 4 IN1 10 3 COM1 Pin 1: LONG LEAD 1 2 NO1 NO2 NC1 V+ COM2 5 Top View Ux Pin 1 Device Marking: Ux for DG2750 x = Date/Lot Traceability Code ORDERING INFORMATION Temp.
