ADG409BRZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG409BRZ-REEL7 is a monolithic CMOS analog multiplexer comprising four differential channels. It switches one of four differential inputs to a common differential output, controlled by two binary address lines (A0, A1) and an enable input (EN). Fabricated on an enhanced LC2MOS process, it supports dual supplies up to ±15 V or a single supply of 12 V. Key electrical parameters include a maximum on-resistance of 100 Ω, a channel-to-channel matching of 15 Ω, and off-isolation of -75 dB at 100 kHz. The device operates within an industrial temperature range of -40°C to +85°C and features break-before-make switching with low charge injection.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process provides extended signal range extending to supply rails and low power dissipation.
• Break-before-make switching action prevents momentary shorting during channel transitions.
• Low charge injection design minimizes transients when switching digital inputs.
• Supports single-supply operation down to 5 V for unipolar applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and reel configuration. The BRZ designation indicates a lead-free, RoHS-compliant component in a 16-lead Narrow Body Small Outline Package. Ensure the REEL7 suffix matches the required tape and reel quantity for automated assembly processes. Cross-reference the manufacturer's current ordering guide to confirm availability and any potential revisions to the datasheet specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring differential signal switching with high isolation and low distortion. The 100 Ω maximum on-resistance and -75 dB off-isolation make it suitable for precision data acquisition. Verify that the logic voltage levels are compatible with the system's control interface. Consider the thermal impedance and power dissipation limits if operating near the upper bounds of the specified temperature range.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the function of the EN input?

The EN input is an active-high digital input used to enable or disable the device. When low, all channels are switched off.

How does the ADG409 handle channel switching?

It exhibits break-before-make switching action, which prevents momentary shorting when switching between channels.

What is the maximum supply voltage rating?

The absolute maximum rating for VDD to VSS is 44 V.
