DG406DN

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406DN is a CMOS analog multiplexer featuring a 1-of-16 configuration housed in a 28-pin PLCC package. It operates with single supplies from +4.5V to +30V or dual supplies from ±4.5V to ±20V. The device guarantees a maximum on-resistance of 100Ω, channel matching within 8Ω, and flatness within 9Ω. Key electrical parameters include a maximum charge injection of 15pC, input leakage current under 5nA at +85°C, and power consumption of 1.25mW max. It supports rail-to-rail signal handling and includes ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DN' corresponds to the 28-pin PLCC package and -40°C to +85°C temperature range. Confirm RoHS compliance status as '+'. Ensure the source document matches the Analog Devices/Maxim Integrated datasheet revision. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 16-channel multiplexing solution is required with tight on-resistance matching specifications. It is suitable for applications needing rail-to-rail signal handling and low charge injection. Verify that the operating voltage range aligns with the system's single or dual supply capabilities. Consider the PLCC package constraints for PCB layout and thermal dissipation requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406/DG407 family of improved CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. The DG406 variant specifically provides a 1-of-16 channel configuration, whereas the DG407 offers a dual 8-channel setup. Both share similar performance characteristics and pinout compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG406DN serves as a direct pin-compatible replacement for legacy industry-standard DG406 devices. Verify that any substitute maintains the 100Ω maximum on-resistance and 15pC charge injection limits to ensure circuit performance parity.
