DG201AESE

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201AESE+ is a quad single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on dual supplies ranging from ±4.5V to ±18V and features a maximum on-resistance of 50 ohms. The device includes two enable inputs for power-down control, reducing supply current to less than 1µA in the disabled state. It offers low charge injection of 12pC and high off-isolation of -74dB at 500kHz. Packaged in a 16-SOIC surface-mount format, it supports an operating temperature range of -25°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices as legacy Maxim products may have limited availability. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when quad SPDT switching is required within a ±18V supply range. Compare on-resistance stability and leakage current against alternative CMOS switches if precision analog performance is critical. Verify package compatibility with existing PCB footprints before finalizing the bill of materials.
