ADG529AKRW

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG529AKRW is a CMOS monolithic analog multiplexer featuring four dual channels. It switches one of four differential inputs to a common differential output based on two binary addresses and an enable input. The device operates within a supply voltage range of 10.8 V to 16.5 V for both single and dual supplies. Key electrical parameters include a maximum on-resistance of 450 Ω, off leakage current of 15 nA, and charge injection of 4 pC. Switching times are specified with a maximum transition time of 300 ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Confirm RoHS compliance status and check for obsolete part notices, as the datasheet indicates the ADG529A series may be discontinued. Ensure packaging specifications match design requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring differential multiplexing with latched address control. Verify that the required supply voltage falls within the 10.8 V to 16.5 V operational range. Consider the package availability, as the K version is typically offered in PLCC or DIP formats. Evaluate thermal dissipation limits if operating at elevated ambient temperatures.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG529AKRW belongs to the ADG528A/ADG529A family of CMOS latched analog multiplexers manufactured by Analog Devices. This family is designed as a superior alternative to legacy DG528/DG529 devices. The ADG529 variant specifically handles differential signals, distinguishing it from the single-ended ADG528 counterpart.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public documentation identifies the ADG528A as a related functional alternative, though it supports single-ended rather than differential configurations. No other specific public substitutes are confirmed in the provided source material.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG529AKRW handle address latching?

The device uses on-chip latches that capture the state of the address control lines and enable input on the rising edge of the Write (WR) signal, allowing for easy microprocessor interfacing.

What is the analog signal range capability?

The enhanced LC2MOS process allows the analog signal range to extend from VSS to VDD, supporting wide supply voltages between 10.8 V and 16.5 V.

Is break-before-make switching guaranteed?

Yes, the switches are guaranteed to be break-before-make, which prevents momentary shorting of input signals during switching transitions.
