DG2788ADN-T1-GE4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2788ADN-T1-GE4 is a four-channel single-pole double-throw (SPDT) analog switch, also configured as two channels of double-pole double-throw (DPDT). It operates on a single power rail from 1.8 V to 5.5 V and features a typical on-resistance of 0.37 Ω at 2.7 V. The device offers a high bandwidth of 338 MHz and a typical propagation delay of 0.1 ns. Key electrical parameters include an off-capacitance of 14.5 pF, an on-capacitance of 26 pF, and a maximum supply current of 60 μA. It supports break-before-make switching and includes power-down protection. The component is housed in a miniQFN-16 package measuring 2.6 mm x 1.8 mm x 0.55 mm.
