ADG411BR

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG411BR is a monolithic CMOS device comprising four independently selectable SPST analog switches. It features an on-resistance of 35 Ω maximum, supply voltage range from ±5 V to ±20 V (dual) or +5 V to +44 V (single), and switching times of tON < 175 ns and tOFF < 145 ns. The device operates with TTL/CMOS-compatible logic, exhibits ultralow power dissipation of 35 μW, and supports analog signal ranges extending to the supply rails.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant (SOIC or TSSOP) and RoHS compliance status indicated by the suffix. Confirm that the ordering code matches the required temperature range and pin configuration. Cross-reference the manufacturer's current ordering guide to ensure the part number is active and available in the desired quantity format.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG411BR for applications requiring low on-resistance and fast switching with minimal power consumption. Ensure the analog signal range fits within the supply rails. Consider the ADG412 if inverted logic control is preferred. Verify thermal management requirements based on the chosen package type and power dissipation limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG411BR belongs to the ADG411/ADG412/ADG413 family of precision quad SPST switches. These devices are designed as plug-in replacements for older DG411/DG412/DG413 series components. The BR suffix typically denotes a 16-lead SOIC_N package variant within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG411BR serves as a direct functional replacement for the Vishay DG411 series. When substituting, verify that the legacy component's pinout and electrical specifications align with the ADG411's enhanced LC2MOS characteristics, particularly regarding on-resistance and switching speeds.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG411 handle analog signals relative to its power supplies?

The ADG411 allows analog signals to extend fully to the supply rails, both in the ON and OFF states, due to its enhanced LC2MOS fabrication process.

What is the primary benefit of the break-before-make switching action?

This feature prevents channel shorting when multiple switches are configured as a multiplexer, ensuring signal integrity during state transitions.

Is the ADG411 compatible with standard digital logic families?

Yes, the device features TTL- and CMOS-compatible digital inputs, simplifying interfacing with standard logic controllers.
