DG406EWI

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406EWI+ is a CMOS analog multiplexer configured as a 1-of-16 single-ended switch. It operates with a +5V to +30V single supply or ±4.5V to ±20V dual supplies. The device features a maximum on-resistance of 175Ω and guaranteed channel matching of 8Ω. Key electrical parameters include a maximum charge injection of 15pC, an input off-leakage current of less than 5nA at +85°C, and a maximum power consumption of 1.25mW. It provides ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWI+' against official documentation to confirm the Wide SOIC package type and -40°C to +85°C industrial temperature range. Ensure that any ordering suffixes do not alter the functional specifications unless explicitly stated in the manufacturer's datasheet. Cross-reference the component marking with the official pinout diagram to prevent installation errors during assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a high-channel-count analog switch is required for signal routing applications. The wide supply voltage range supports both single and dual rail configurations. Verify that the 175Ω on-resistance meets the system's signal integrity requirements. Confirm that the digital control interface aligns with the available logic levels in the host circuit design.

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 16-channel configuration, whereas the DG407 offers a dual 8-channel setup. Both share identical pinouts and core performance characteristics, facilitating direct replacement in existing designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG406EWI+ serves as a direct pin-compatible replacement for legacy industry-standard DG406 devices. Designers should verify that the upgraded electrical parameters, such as reduced leakage and improved resistance matching, are compatible with the original circuit constraints.
