DG403AK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403AK is a dual, high-speed analog switch manufactured by Analog Devices Inc. (Maxim Integrated). It features two independent single-pole double-throw (SPDT) switches in a 16-pin CDIP package. The device operates with a maximum on-resistance of 30 Ohms and supports supply voltages ranging from 10 V to 30 V for single supplies or ±5 V to ±18 V for dual supplies. Switching times are specified at a maximum of 150 ns for turn-on and 100 ns for turn-off. It functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'AK' against the manufacturer's current product lifecycle status, as older variants may be discontinued or subject to limited availability. Confirm that the 16-lead ceramic dual in-line package meets the thermal and mechanical requirements of the target design. Ensure compatibility with existing PCB footprints and assembly processes before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated analog channels are required with fast switching speeds. The 30 Ohm on-resistance suits applications demanding low insertion loss. Consider the through-hole CDIP package for prototyping or high-reliability environments where surface mount options are unsuitable. Validate that the voltage range aligns with the system's power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG403AK belongs to the DG403 series of improved dual high-speed analog switches. This family is designed for applications requiring precise signal routing with minimal distortion. The device complements other Maxim Integrated analog switches by offering a balance of speed and low on-resistance in a robust ceramic package suitable for industrial and military-grade environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG403CY+T and DG403DY+ for surface-mount implementations. For pin-compatible replacements, verify the DG403AK datasheet for equivalent electrical parameters. Cross-reference with the DG303 series if TTL compatibility is a primary requirement, noting differences in switching speed and resistance.
