ADG451BRZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG451BRZ-REEL is a monolithic CMOS analog switch IC containing four independently selectable single-pole/single-throw (SPST) switches. Fabricated on an enhanced LC2MOS process, it features a maximum on resistance of 5 Ω and ultralow power dissipation of 18 μW. The device supports dual supplies from ±4.5 V to ±20 V or a single supply as low as 5.0 V. It operates within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum switching time of 180 ns for turn-on and 140 ns for turn-off, with a continuous current rating of 100 mA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process technology providing low power dissipation and high switching speed.
• Flat on resistance profile over the full analog input range ensuring excellent linearity.
• TTL- and CMOS-compatible digital control logic for direct interface with standard logic families.

Analog Switches, Multiplexers, Demultiplexers Applications

• Relay replacement in signal routing circuits
• Audio and video signal switching systems
• Precision data acquisition and sample-and-hold applications
• Automatic test equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on resistance and flatness are critical for signal integrity. The ADG451 utilizes non-inverted logic, requiring a logic low to activate the switches. Consider the ADG452 if inverted logic control is preferred, or the ADG453 if break-before-make switching action is required for multiplexer configurations.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG451/ADG452/ADG453 family of quad SPST analog switches. It serves as a pin-compatible upgrade for older ADG411/ADG412/ADG413 and ADG431/ADG432/ADG433 series devices. The family shares similar electrical characteristics but differs in digital control logic polarity and switching timing behavior.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG451BR is a tube-packaged equivalent of the same functional device. The ADG451BRZ-REEL7 is another reel variant within the same package family. Verify that any substitute maintains the 5 Ω maximum on resistance and compatible voltage ratings.
