ADG211AKR-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG211AKR-REEL7 is a monolithic CMOS device comprising four independently selectable SPST switches fabricated on an enhanced LC2MOS process. It supports an analog signal range of ±15 V and operates from single or dual supplies up to 44 V maximum rating. Key electrical parameters include a maximum on-resistance (RON) of 115 Ω, typical leakage current of 0.5 nA, and charge injection of 20 pC. Switching speeds feature a maximum tON of 600 ns and tOFF of 450 ns. The device offers break-before-make switching action and maintains TTL/CMOS compatibility within an extended temperature range of −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process enables high breakdown voltage and increased analog signal handling capability of ±15 V.
• Supports single supply operation for unipolar signals while maintaining low leakage currents suitable for precision circuits.
• Inherent break-before-make switching action minimizes leakage errors when multiple outputs are tied together in multiplexer applications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Multiplexer systems requiring minimal leakage errors with tied outputs.
• Precision measurement circuits utilizing low leakage characteristics.
• Signal routing in instrumentation where high breakdown voltage is required.
• Data acquisition systems compatible with TTL/CMOS logic levels.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as REEL7 indicates tape and reel packaging distinct from tube variants. Confirm RoHS compliance status via the manufacturer's documentation, as indicated by the Z suffix in related part numbers. Ensure the component matches the required SOIC-16 package dimensions for PCB layout integration. Cross-reference the datasheet revision to validate specifications against current production standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG211AKR-REEL7 for applications requiring four independent SPST switches with high signal integrity. Choose this part over the ADG212A variant if non-inverted digital control logic is preferred. Consider the extended LC2MOS process benefits for environments demanding higher voltage tolerance. Evaluate the 115 Ω maximum on-resistance against circuit loss requirements. Verify that the 600 ns switching speed meets the system timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG211A belongs to the Analog Devices LC2MOS Quad SPST Switches family, designed for robust analog signal routing. It serves as a pin-compatible replacement for legacy DG211 devices, facilitating design upgrades without board redesign. The series emphasizes low charge injection and high isolation, making it suitable for complex multiplexing architectures. The KRZ suffix denotes a RoHS-compliant 16-lead SOIC package version within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG211AKR-REEL7 is explicitly noted as pin-compatible with the DG211/DG212 series. Designers replacing these older components should verify that the improved LC2MOS process characteristics align with existing thermal and electrical margins. No other direct substitutes are confirmed in the provided documentation.
