DG403DY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403DY+ is a dual, high-speed analog switch featuring two single-pole/double-throw (SPDT) channels in a 16-pin Narrow SO package. It operates from a single +10V to +30V supply or bipolar supplies of ±4.5V to ±20V. The device guarantees low on-resistance matching between switches (2 Ω max) and on-resistance flatness over the signal range (3 Ω max). Typical on-resistance is 20 Ω with a maximum of 45 Ω. Switching times are 150 ns for turn-on and 100 ns for turn-off. Power consumption is limited to 35 µW, and it supports rail-to-rail signal handling with TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features improved on-resistance matching between channels and guaranteed on-resistance flatness over the signal range.
• Offers low charge injection and reduced off-leakage current across temperature variations.
• Supports both single-supply and bipolar power configurations with rail-to-rail signal handling capability.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'DY+' corresponds to the specific 16-pin Narrow SOIC package and -40°C to +85°C operating temperature range. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the component source matches Analog Devices / Maxim Integrated specifications before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching functionality is required within a compact surface-mount footprint. The device is suitable for applications demanding low power consumption and fast switching speeds. Verify that the required analog signal voltage range falls within the specified single or bipolar supply limits to ensure proper operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG401/DG403/DG405 series of improved, dual, high-speed analog switches. The DG403 variant specifically provides two SPDT switches, distinguishing it from the DG401's dual SPST and DG405's dual SPST normally-open configuration. All variants share similar electrical characteristics and fabrication processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement options include other parts within the DG401/DG403/DG405 family that match the pinout and electrical specifications. Verify package compatibility and temperature range requirements when substituting with equivalent components from the same manufacturer series.
