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 an on-resistance of 45Ω max and a channel-to-channel match of 2Ω max. Switching times are 150ns for turn-on and 100ns 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 suffix 'DJ' confirms the 16-pin Plastic DIP package and the 0°C to +70°C operating temperature range. Confirm RoHS compliance status as older manufacturing runs may differ. Ensure the source document matches the Analog Devices / Maxim Integrated datasheet revision for accurate electrical parameters.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual DPST analog switch is required within a standard DIP footprint. It is suitable for applications needing rail-to-rail signal swing and fast switching speeds under moderate temperature conditions. Verify that the 45Ω on-resistance meets the system's signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG401/DG403/DG405 family of improved, dual, high-speed analog switches. The DG405 variant specifically provides two independent DPST switches, distinguishing it from the single SPST DG401 and the dual SPDT DG403 models within the same series.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance flatness over the signal range?

The on-resistance flatness (rFLAT(ON)) is guaranteed to be a maximum of 3Ω over the specified analog signal range.

How does the device handle overvoltage conditions?

Signals on S, D, or IN exceeding V+ or V- are clamped by internal diodes. External blocking diodes can be added for protection if proper power-supply sequencing is not possible.

What is the typical charge injection value?

The charge injection is typically 10pC and is guaranteed to be a maximum of 15pC under specified test conditions.
