ADG428BRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG428BRZ is a monolithic CMOS analog multiplexer from Analog Devices, featuring eight single-ended channels. It operates with a maximum supply voltage of 44 V and supports both single and dual power configurations. The device utilizes LC2MOS technology to achieve low on-resistance and minimal charge injection. Digital inputs are TTL-compatible, facilitating direct microprocessor interfacing through on-chip address latches. The component is housed in an 18-pin Small Outline IC (SOIC) package and functions within an industrial temperature range of -40°C to +85°C.

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 high switching speed and low power dissipation.
• TTL-compatible control inputs ensure compatibility across the full specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'BRZ' against the manufacturer's ordering guide to confirm the SOIC-18 package and industrial temperature grade. Ensure that the application environment remains within the specified absolute maximum ratings for supply voltage and current limits to prevent permanent damage. Confirm RoHS compliance status if required by local regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring eight single-ended analog signal paths with TTL-compatible digital control. The internal latches reduce board space requirements compared to non-latched alternatives. Verify that the system's analog signal range extends to the supply rails, as supported by the enhanced LC2MOS process specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG428/ADG429 family of latchable analog multiplexers. The ADG428 variant specifically handles eight single channels, whereas the ADG429 manages four differential channels. Both share the same underlying LC2MOS fabrication technology and serve as improved replacements for legacy DG428/DG429 models.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the ADG428/ADG429 as improved replacements for the DG428/DG429 Analog Multiplexers. Designers transitioning from these legacy parts should verify pinout compatibility and electrical parameter alignment.
