DG2788, DG2789 Vishay Siliconix Low Voltage, Low On-Resistance, Dual DPDT/Quad SPDT Analog Switch DESCRIPTION The DG2788, DG2789 are monolithic CMOS analog switching products designed for high performance switching of analog signals. Combining low power, high speed, low on-resistance and small physical size, the DG2788, DG2789 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2788, DG2789 are built on Vishay Siliconix’s low voltage process. An epitaxial layer prevents latchup. Breakbefore-make is guaranteed. The switch conducts equally well in both directions when on, and blocks up to the power supply level when off. The DG2788 is configured as a dual Double Pole Double Throw switches while the DG2789 is configured as a Quad Single Pole Double Throw. The DG2789 has one control pin for all four SPDT switches and also has an enable pin that can turn all switches off. The DG2788 and DG2789 comes in a small miniQFN-16 lead package (2.6 x 1.8 x 0.75 mm). As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations and is 100 % RoHS compliant.
