DG405DJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405DJ+ is a dual, high-speed analog switch featuring two double-pole/single-throw (DPST) channels in a 16-pin Plastic DIP package. It operates from single +10V to +30V or bipolar ±4.5V to ±20V supplies with a maximum power consumption of 35µW. The device guarantees low on-resistance matching between switches (2Ω max) and flatness over the signal range (3Ω max). Typical on-resistance is 20Ω, with a maximum of 45Ω for the C/D suffix. Switching times are 150ns max for turn-on and 100ns max for turn-off. It supports rail-to-rail signal handling and maintains TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and temperature range. The 'DJ' suffix indicates a 16-pin Plastic DIP package with an operating temperature range of 0°C to +70°C. Confirm RoHS compliance status as '+', and ensure the component meets the required absolute maximum ratings for your application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual DPST switching is required with tight on-resistance matching specifications. Ensure the supply voltage range aligns with the +10V to +30V single or ±4.5V to ±20V bipolar options. Verify that the 150ns turn-on time and 100ns turn-off time meet system timing requirements. Consider the 16-pin DIP package constraints for PCB layout and thermal dissipation limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG405DJ+ belongs to the redesigned DG401/DG403/DG405 series by Analog Devices / Maxim Integrated. This family offers improved performance over previous generations, specifically regarding on-resistance matching and flatness. The DG405 variant specifically provides two DPST switches, distinguishing it from the SPST DG401 and SPDT DG403 models within the same pin-compatible footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other suffixes of the DG405 series such as DG405CY (Narrow SOIC) or DG405DK (CERDIP), provided the package and temperature range match the design requirements. Cross-family upgrades may require schematic review due to potential differences in pinout or electrical characteristics.
