DG211CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211CSE+ is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally closed configuration and operates on dual power supplies ranging from ±4.5V to ±18V. The device utilizes monolithic low-power CMOS technology, eliminating the need for a third VL supply. Electrical specifications include a maximum drain-source ON-resistance of 175 Ohms at ±10V and a maximum turn-on time of 1000ns. It supports continuous currents up to 20mA and peak pulsed currents of 70mA. The component is housed in a 16-pin SOIC package with an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' against official distributor catalogs to confirm the 16-SOIC package and commercial temperature grade. Ensure compatibility with existing PCB footprints for SOIC-16 components. Cross-reference part numbers with Analog Devices or Maxim Integrated databases to validate authenticity and revision levels before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally closed SPST switching within a ±4.5V to ±18V supply range. Consider the DG211 over the DG201A when slower switching speeds are acceptable but lower power consumption is prioritized. Verify that the 175 Ohm maximum ON-resistance meets circuit requirements. Ensure the design accommodates the absence of a VL pin compared to legacy equivalents.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG211 belongs to the DG201A/DG211 family of quad SPST CMOS analog switches. It shares architectural similarities with the DG201A but differs primarily in switching speed characteristics. The DG211 offers slower transition times compared to the DG201A but maintains comparable power efficiency. This family is designed to replace older discrete solutions or previous generation ICs with improved latch-up protection and simplified power supply requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG201A is a functionally similar switch within the same family, distinguished by faster switching speeds (600ns max turn-on). Other variants in the series include DG211EUE+ for extended temperature ranges and different packages. Verify pinout compatibility and electrical parameter tolerances when substituting.
