The DG2037/2038/2039 are dual single-pole/single-throw monolithic CMOS analog switches designed for high performance switching of analog signals. Combining low power, fast switching, low on-resistance (rDS(on): 3.0 m@ 2.7 V) and small physical size, the DG2037/2038/2039 are ideal for portable and battery powered applications requiring high performance and efficient use of board space.
The document describes the DG2037/2038/2039 as dual single-pole/single-throw monolithic CMOS analog switches designed for high-performance switching of analog signals. These devices are built on a new high-density low-voltage process and feature an epitaxial layer to prevent latchup, allowing them to conduct equally well in both directions when on.
