ADG453BRZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG453BRZ-REEL7 is a monolithic CMOS device comprising four independently selectable single-pole/single-throw (SPST) switches. It features an enhanced LC2MOS process providing low power dissipation, high switching speed, and low on resistance. The analog signal range extends to the supply rails, supporting both single-supply operation (as low as 5.0 V) and dual-supply operation (±4.5 V to ±20 V). The device exhibits break-before-make switching action for multiplexer applications and includes TTL-/CMOS-compatible digital control logic.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching prevents channel shorting in multiplexer configurations.
• Enhanced LC2MOS process ensures ultralow power dissipation suitable for battery-powered systems.
• Analog signal range fully extends to the supply rails for maximum dynamic range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm authenticity. Ensure the package matches the specified 16-Lead Standard Small Outline Package (R-16). Check that the suffix indicates Pb-free construction if required by environmental standards. Confirm the operating temperature range aligns with industrial specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when break-before-make timing is critical for multiplexer applications to avoid signal contention. Choose the B version for extended industrial temperature ranges. Verify that the logic control requirements match the specific inversion characteristics of the ADG453 variant compared to other family members.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG451/ADG452/ADG453 series of quad SPST analog switches. The ADG453 variant is distinguished by its mixed digital control logic, where two switches follow one logic polarity and the other two follow the inverted polarity. This configuration facilitates specific multiplexing topologies without external logic inversion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible upgrades include the ADG411, ADG412, ADG413, ADG431, ADG432, and ADG433. Verify functional differences such as logic inversion and switching speeds before substituting these models.

Analog Switches, Multiplexers, Demultiplexers FAQ

What distinguishes the ADG453 from the ADG451 and ADG452?

The ADG453 features mixed digital control logic: two switches operate with standard logic while the other two use inverted logic. The ADG451 uses all inverted logic, and the ADG452 uses all non-inverted logic.

Does the ADG453 support single-supply operation?

Yes, the device can operate from a single rail power supply as low as 5.0 V, in addition to dual supplies ranging from ±4.5 V to ±20 V.

What is the purpose of the break-before-make feature in this device?

The break-before-make switching action prevents channel shorting when the switches are configured as a multiplexer, ensuring signal integrity during state transitions.
