DESCRIPTION

The DG2788A, is a four-channel single-pole double-throw

(SPDT) analog switch with two control inputs. It is also

known as a two-channel double-pole double-throw (DPDT)

configuration. The part is designed to operate from 1.8 V to

5.5 V single power rail. All switches conduct equally well in

both directions, offering rail to rail signal switching and can

be used both as multiplexers as well as de-multiplexers.

The DG2788A offers low parasitic capacitance and highly

matched low and flat switch resistance over the full signal

range. It features break-before-make switching and low

control logic threshold. The part supports rail to rail fast

edge pulsing signals and have 0.1 ns/typ. propagation

delay. It is ideal for both analog and digital signal switching

in space constrain applications requiring high performance

and efficient use of board space.

The DG2788A comes in a small miniQFN-16 lead package

of 2.6 mm x 1.8 mm x 0.55 mm.
