ADG211AKRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG211AKRZ is a monolithic CMOS device comprising four independently selectable SPST switches, fabricated on an enhanced LC2MOS process. It supports analog signal ranges up to ±15 V and operates from single or dual supplies within a −40°C to +85°C temperature range. Key electrical parameters include a maximum on-resistance (RON) of 115 Ω, typical leakage currents of 0.5 nA, and a maximum power dissipation of 470 mW. The device features TTL/CMOS compatible logic inputs, with switching times of 600 ns (tON) and 450 ns (tOFF). It is housed in a 16-lead SOIC package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS technology enables high breakdown voltage and extended analog signal handling capability of ±15 V.
• Inherent break-before-make switching action minimizes transients and leakage errors when multiple outputs are tied together.
• Low charge injection design reduces signal transients during digital input switching for improved precision.
• TTL and CMOS compatible control logic allows direct interfacing with standard digital systems.

Analog Switches, Multiplexers, Demultiplexers Applications

• Multiplexer applications requiring low leakage and break-before-make switching.
• High precision circuits utilizing low leakage current characteristics.
• Signal routing in systems requiring ±15 V analog signal ranges.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and compliance status. The 'KRZ' suffix indicates a 16-lead SOIC package that is RoHS compliant. Confirm availability through authorized distributors as supply status may vary. Ensure the selected variant matches the required thermal and mechanical specifications for the target application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG211AKRZ for applications requiring four independent SPST switches with high voltage tolerance. Compare against the ADG212A if non-inverted control logic is preferred. Consider the DG211 series for pin-compatible alternatives with different performance profiles. Verify that the 115 Ω maximum RON meets the signal integrity requirements of the circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG211AKRZ belongs to the ADG211A/ADG212A family of quad SPST switches from Analog Devices. This family utilizes LC2MOS technology to provide robust signal handling in a compact form factor. The component is designed to replace legacy parts like the DG211 while offering improved performance metrics such as lower leakage and higher voltage ratings.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG211CSE+T and DG211EUE+ are pin-compatible substitutes within the same manufacturer portfolio. These alternatives share similar functional architectures but may exhibit differences in on-resistance, leakage, and operating temperature ranges. Verify datasheet specifications before substitution.
