ADG452BRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG452BRZ is a monolithic CMOS analog switch IC containing four independent 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 ranging 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 and offers fast switching times with a maximum turn-on time of 180 ns and turn-off time of 140 ns.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process provides high switching speed and low on resistance.
• Digital control logic requires a logic high input to activate the switches.
• Ultralow power dissipation makes the component suitable for battery-powered instruments.
• Fully specified for operation at ±5 V, 12 V, and ±15 V supply voltages.

Analog Switches, Multiplexers, Demultiplexers Applications

• Relay replacement
• Audio and video switching
• Automatic test equipment
• Precision data acquisition
• Sample-and-hold systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix Z indicates a lead-free part compliant with RoHS standards. Confirm the package type matches the required board layout, as the BRZ designation corresponds to the SOIC-16 narrow body package. Ensure the design accounts for the specific logic polarity where a high signal activates the channel.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when inverted digital control logic is required compared to the ADG451. Verify that the application utilizes unipolar or bipolar signals within the specified supply ranges. Consider the ADG453 if break-before-make switching action is necessary for multiplexer configurations to prevent channel shorting.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG451/ADG452/ADG453 family of LC2MOS switches. It serves as a pin-compatible upgrade for older ADG411/ADG412/ADG413 and ADG431/ADG432/ADG433 series devices. The primary distinction within the family is the digital control logic inversion between the ADG451 and ADG452 variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include ADG451BRZ and ADG453BRZ. These parts share identical pinouts and electrical characteristics, differing only in control logic polarity or switching action.
