ADG419BR-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG419BR-REEL7 is a monolithic CMOS SPDT analog switch fabricated on an enhanced LC2MOS process. It operates with dual supplies up to ±16.5 V or a single supply of 12 V. Key electrical parameters include a maximum on-resistance of 35 Ω, transition time of 160 ns, and power dissipation under 35 μW. The device supports signal ranges extending to the supply rails, offers break-before-make switching, and maintains low leakage currents.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix REEL7 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the B version temperature rating of -40°C to +125°C aligns with the intended industrial operating environment. Ensure logic voltage levels are compatible with the specified VL requirements for reliable digital control.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and flat on-resistance are critical for signal integrity. The LC2MOS technology makes it suitable for portable applications due to minimal power consumption. Consider the 160 ns transition time for bandwidth limitations in high-speed sampling circuits. Verify compatibility with existing logic families regarding input voltage thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG419 family of precision mini-DIP analog switches manufactured by Analog Devices Inc. It serves as a plug-in replacement for legacy DG419 devices. The BR-REEL7 designation indicates the surface-mount SOIC package variant supplied in reel form, distinct from through-hole DIP options within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly identifies the ADG419 as a direct plug-in replacement for the DG419. Designers upgrading from older discrete or alternative IC solutions should verify pinout compatibility and ensure that the new switch's leakage characteristics meet the specific noise floor requirements of the application.
