ADG526AKN

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG526AKN is a CMOS monolithic analog multiplexer featuring 16 single channels. It operates within a wide supply range of 10.8 V to 16.5 V for both single and dual configurations. The device exhibits a maximum on-resistance of 450 Ω, an off-input leakage current of 1 nA, and a charge injection of 4 pC. Switching times are specified at 300 ns for both turn-on and turn-off. It functions across an extended temperature range from −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• On-chip latches facilitate direct microprocessor interfacing via WR and RS signals.
• Enhanced LC2MOS process provides an increased analog signal range from VSS to VDD.
• Break-before-make switching guarantees protection against momentary input shorting.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The 'KN' designation indicates a 28-lead Plastic Dual In-Line Package (PDIP) with an extended commercial temperature range. Confirm RoHS compliance requirements, as non-Z suffixes may not meet current environmental standards. Ensure the design accommodates the required lead spacing and thermal characteristics for through-hole mounting.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a high-channel-count single-ended multiplexer is required. The ADG526A is suitable for applications needing break-before-make timing to prevent signal cross-talk. Compare against the ADG527A if differential signaling is necessary instead of single-ended paths. Consider the PDIP package constraints regarding board space compared to surface-mount alternatives like SOIC or PLCC.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG526A/ADG527A family of CMOS latched analog multiplexers. These devices serve as superior alternatives to legacy DG526 and DG527 models. The family utilizes enhanced LC2MOS technology to support wide supply voltages and robust signal ranges. The ADG526A specifically handles 16 single channels, while the ADG527A manages dual 8-channel differential configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public documentation identifies the DG526 and DG527 as legacy predecessors. The ADG526A offers improved specifications over these older models. Verify pin compatibility and electrical parameters before substituting. No other direct public substitutes are confirmed in the provided datasheet.
