DG405DY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405DY is a dual, high-speed analog switch featuring two double-pole/single-throw (DPST) channels in a 16-pin Narrow SO package. It operates from single +10V to +30V or bipolar ±4.5V to ±20V supplies with a maximum power consumption of 35µW. The device guarantees low on-resistance matching between switches (2Ω max) and flatness over the signal range (3Ω max). Typical on-resistance is 20Ω, with a maximum of 45Ω for the C/D temperature grades. Switching times are 150ns max for turn-on and 100ns max for turn-off. Charge injection is limited to 15pC max, and off-leakage current is less than 5nA at +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact temperature range and package variant. Ensure that the selected component meets all absolute maximum ratings regarding supply voltage sequencing and input signal clamping to prevent permanent damage during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent analog switching is required with tight on-resistance matching specifications. Consider the 16-pin Narrow SO package for surface-mount applications. Verify that the operating temperature range aligns with the system environment, as the 'D' suffix indicates an extended range compared to standard industrial grades.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG405DY belongs to the redesigned DG401/DG403/DG405 family of improved dual high-speed analog switches. These devices utilize a 44V silicon-gate process to enhance performance metrics such as leakage current and charge injection compared to previous industry-standard versions while maintaining pin compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other variants within the DG401/DG403/DG405 family, such as DG405CY or DG405DJ, provided the package type and temperature range requirements are met. Cross-family upgrades may require schematic adjustments due to differing pinouts or electrical characteristics.
