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. Key electrical parameters include a maximum on-resistance of 45Ω, an on-resistance match between channels of 2Ω max, and on-resistance flatness of 3Ω max. Switching times are 150ns for turn-on and 100ns for turn-off, with a break-before-make delay of 20ns max. The device exhibits low charge injection of 15pC max and off-leakage current less than 5nA at +85°C. Power consumption is limited to 35µW max, and it supports rail-to-rail signal handling.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as the base model may differ from leaded variants. Check for obsolescence notices or production change notifications prior to procurement. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching with high speed and low distortion is required. Verify that the 45Ω on-resistance meets circuit impedance requirements. Ensure supply voltages remain within the specified single or bipolar ranges. Consider thermal dissipation limits based on ambient temperature and PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG403DY belongs to the DG401/DG403/DG405 family of improved dual high-speed analog switches. It shares architectural similarities with the DG401 (dual SPST) and DG405 (dual DPST), differing primarily in channel configuration. The device utilizes a 44V silicon-gate process for robust operation and reliability in demanding analog switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement options include the DG403DJ for through-hole DIP packaging. Other variants within the DG403 series offer different temperature ranges or package types. Verify pin compatibility and electrical parameter equivalence before substituting with components from other manufacturers.
