ADG4612BRUZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG4612BRUZ-REEL7 is a quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It operates with a single supply voltage ranging from 3 V to 12 V or dual supplies of ±3 V to ±5.5 V. The device features power-off protection, ensuring switches remain off and inputs stay high impedance when supplies are absent. Maximum on-resistance is specified at 6.1 Ω under dual supply conditions and 5.1 Ω under 12 V single supply. It supports overvoltage protection up to 16 V and negative signal capability down to −5.5 V. The component is housed in a 16-lead TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Power-off protection ensures switches remain off and inputs maintain high impedance when power supplies are absent.
• Overvoltage protection allows blocking of signal levels up to 16 V even during fault conditions.
• Negative signal capability enables the passage of signals down to −5.5 V relative to ground.
• Low on-resistance profile provides excellent linearity and low distortion for audio and data acquisition applications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Hot swap applications
• Data acquisition systems
• Battery-powered systems
• Automatic test equipment
• Relay replacement

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the reel packaging format required for automated assembly processes. Confirm that the TSSOP-16 package dimensions align with the target PCB footprint. Ensure the operating temperature range of −40°C to +105°C meets the environmental requirements of the final design. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring robust power-off protection and rail-to-rail signal handling. The 6.1 Ω maximum on-resistance makes it suitable for low-distortion audio paths. Verify logic compatibility with 3 V control inputs if interfacing with standard digital logic. Consider the thermal resistance of the TSSOP package when determining continuous current limits per channel.
