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 procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the part number with the latest datasheet revision to confirm compliance with current environmental standards and pin configurations before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low on resistance and fast switching speeds within a compact surface-mount footprint. Consider the ADG451 variant specifically for its non-inverted digital control logic compared to the ADG452. Evaluate the operating temperature range and supply voltage requirements to ensure compatibility with the system's power rails and environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG451BRUZ-REEL7 belongs to the ADG451/ADG452/ADG453 family of analog switches. These devices are designed as pin-compatible upgrades for older series such as the ADG411/ADG412/ADG413 and ADG431/ADG432/ADG433. The BRUZ suffix indicates a Pb-free version in a 16-lead Thin Shrink Small Outline Package (TSSOP), while the REEL7 designation specifies the tape and reel packaging format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include ADG451BRZ-REEL7 and ADG451BR-REEL7. Verify that the alternative package options match the PCB layout requirements and thermal characteristics of the original design.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the ADG451 and ADG452?

The ADG451 and ADG452 differ only in their digital control logic inversion. The ADG451 switches turn on with a logic low input, whereas the ADG452 requires a logic high input to activate the switches.

Does the ADG451 support break-before-make switching?

No, the ADG451 does not exhibit break-before-make switching action. This feature is inherent only in the ADG453 variant, which is designed for multiplexer applications to prevent channel shorting.

What is the maximum analog signal range supported by the ADG451?

The ADG451 supports an analog signal range that extends to the supply rails, with a maximum rating of ±15 V. The absolute maximum ratings allow for a total supply voltage difference of up to 44 V.
