ADG419BN

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG419BN is a monolithic CMOS single-pole double-throw (SPDT) analog switch fabricated on an enhanced LC2MOS process. It operates with dual supplies ranging from ±5 V to ±16.5 V or a single supply up to 13.2 V. The device features a maximum on-resistance of 35 Ω and ultralow power dissipation below 35 μW. Transition times are limited to 160 ns, while off-leakage currents remain low at 250 nA maximum. It supports signal ranges extending to the supply rails.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify RoHS compliance status when selecting variants, as suffixes indicate environmental attributes. Confirm package type availability, as the BN designation corresponds to a specific through-hole configuration. Ensure logic voltage levels match system requirements, as the device specifies distinct input thresholds for reliable operation across temperature ranges.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high linearity and flat on-resistance profiles over the full analog input range. Consider the extended signal range feature if bipolar signals must interface directly with supply rails without level shifting. Evaluate thermal constraints, as power dissipation limits vary by package style and ambient operating conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG419 belongs to the ADG41x family of precision analog switches manufactured by Analog Devices. It serves as a direct plug-in replacement for legacy DG419 devices. The family utilizes LC2MOS technology to balance low power consumption with fast switching speeds and high isolation characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly identifies the ADG419 as a plug-in replacement for the DG419. Designers should verify pinout compatibility and ensure that the replacement part meets the specific voltage and current ratings required by the existing circuit design.

Analog Switches, Multiplexers, Demultiplexers FAQ

Can the ADG419 operate with a single power supply?

Yes, the device can operate from a single rail power supply. It is fully specified with a single 12 V supply and remains functional with single supplies as low as 5 V.

What is the maximum supply voltage rating?

The absolute maximum rating for the voltage difference between VDD and VSS is 44 V.

How does the ADG419 handle signal transitions?

The device exhibits break-before-make switching action, which ensures that one channel turns off before the other turns on, preventing signal shorting during transitions.
