Analog Switch DGQ2788A
Automotive 125 °C Analog Switch, Dual DPDT / Quad SPDT, 0.37 Ω, 338 MHz Bandwidth
The DGQ2788A, 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 DGQ2788A 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 DGQ2788A comes in a small miniQFN-16 lead package of 2.6 mm x 1.8 mm x 0.55 mm.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
