ADG428BP-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG428BP-REEL is a monolithic CMOS analog multiplexer featuring eight single channels. It operates with a maximum supply rating of 44 V and supports both single (+5 V to +15 V) and dual (±5 V to ±15 V) power configurations. The device exhibits a typical on-resistance of 60 Ω, low charge injection of less than 4 pC, and fast switching times with a break-before-make action. Digital inputs are TTL-compatible, facilitating direct microprocessor interfacing.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• On-chip address and control latches simplify digital interface design for bus-controlled systems.
• Break-before-make switching action prevents momentary shorting during channel transitions.
• Enhanced LC2MOS process provides extended signal range extending to the supply rails.

Analog Switches, Multiplexers, Demultiplexers Applications

• Automatic Test Equipment
• Data Acquisition Systems
• Communication Systems
• Avionics and Military Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the REEL suffix indicates tape-and-reel packaging suitable for automated assembly processes. Confirm the B-version designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the specific PLCC package dimensions required by the target PCB footprint.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when latchable address inputs are required to reduce board space and simplify control logic. It serves as a plug-in replacement for legacy DG428 devices. Consider the extended signal range capability for applications requiring analog signals to approach the supply rails without distortion.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG428/ADG429 family of high-performance analog multiplexers manufactured by Analog Devices. The ADG428 variant specifically handles eight single-ended channels, whereas the ADG429 manages four differential channels. Both utilize the same enhanced LC2MOS technology for low power and high speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the ADG428 as a direct plug-in replacement for the DG428 analog multiplexer. Designers upgrading from older generations should verify pinout compatibility and ensure that the improved electrical characteristics meet the system requirements.
