ADG528AKN

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG528AKN is a CMOS latched analog multiplexer featuring eight single-ended channels. It operates within a wide supply range of 10.8 V to 16.5 V for both single and dual configurations. The device provides an on-resistance (Ron) maximum of 450 Ω at ±15 V supplies, with a typical value of 280 Ω. Switching times are specified with a maximum transition time of 300 ns and a turn-on time of 300 ns. Off-state leakage current is limited to a maximum of 100 nA. The component supports break-before-make switching and includes on-chip latches for microprocessor interfacing.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• On-chip address and enable latches facilitate direct microprocessor interfacing via WR and RS signals.
• Break-before-make switching action prevents momentary shorting between input signals.
• Enhanced LC2MOS process enables operation across the full VSS to VDD analog signal range.
• Low leakage currents in the pA range support high-precision circuit applications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal selection.
• Industrial control interfaces utilizing microprocessor-compatible logic levels.
• Test and measurement equipment needing low-leakage signal routing.
• Process control instrumentation operating in extended temperature environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type, as the ADG528AKN denotes an 18-lead plastic DIP. Confirm RoHS compliance status if lead-free construction is mandatory for the assembly process. Ensure the voltage ratings align with the system's power supply specifications before integration. Check for any updated revision history notes regarding pin configuration or electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when eight single-ended channels are required with integrated latching functionality. The ADG528AKN is suitable for designs needing wide supply voltage tolerance and low off-state leakage. Compare the 450 Ω maximum on-resistance against load requirements to ensure signal integrity. Consider the 18-lead DIP package constraints for PCB layout and thermal management in the final design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG528AKN belongs to the ADG528A family of CMOS latched analog multiplexers manufactured by Analog Devices Inc. This series serves as a superior alternative to legacy DG528 devices. The family includes variants such as the ADG529A for differential applications, though the ADG529A is noted as obsolete. The ADG528A series is designed for robust performance in industrial and commercial environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG528A is explicitly documented as a superior alternative to the DG528. Designers replacing older DG528 components should verify pin compatibility and electrical parameter alignment. No other public substitutes are confirmed in the provided documentation.
