DG2788ADN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2788ADN-T1-E4 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 supports rail-to-rail signal switching. The device features a typical on-resistance of 0.37 Ω at 2.7 V, with a maximum of 0.6 Ω across the full temperature range. It offers a -3 dB bandwidth of 338 MHz and a typical propagation delay of 0.1 ns. Key electrical parameters include an off-isolation of -82 dB at 100 kHz, crosstalk of -61 dB at 1 MHz, and a charge injection of -245 pC. The component is housed in a miniQFN-16 package measuring 2.6 mm x 1.8 mm x 0.55 mm.
