ADG433BRZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG433BRZ-REEL is a precision quad SPST analog switch from Analog Devices, housed in a 16-lead SOIC package. It features an on-resistance of 24 Ω maximum and operates with dual supplies up to ±16.5 V or a single supply up to 13.2 V. The device supports signal ranges extending to the supply rails, with switching times of 165 ns (tON) and 130 ns (tOFF). It exhibits low leakage currents (<0.25 nA), charge injection of 5 pC, and channel-to-channel crosstalk of -85 dB at 1 MHz. Power dissipation is 7.7 µW max under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents channel shorting in multiplexer configurations.
• Enhanced LC2MOS process provides ultralow power dissipation suitable for battery-powered systems.
• Flat on-resistance profile ensures excellent linearity and low distortion for audio signals.
• TTL/CMOS compatible digital control logic simplifies interface design.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's current documentation to confirm packaging format and quantity. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times prior to procurement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG433BRZ-REEL when mixed logic control is required, as two switches use active-high logic while the other two use active-low logic. This configuration differs from the ADG431 and ADG432, which have uniform logic polarity across all channels. Verify that the 24 Ω on-resistance and 165 ns switching speed meet the system timing and impedance requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG433 is part of the ADG431/ADG432/ADG433 family of monolithic CMOS switches. It serves as a plug-in replacement for older DG411/DG412/DG413 devices. The BRZ suffix indicates a lead-free, RoHS-compliant variant in a tube or reel package, manufactured by Analog Devices Inc.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed direct substitutes include the ADG431BRZ-REEL and ADG432BRZ-REEL. Note that these variants differ in digital control logic polarity compared to the ADG433. Verify logic compatibility before substitution.
