ADG211AKR-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG211AKR-REEL is a quad SPST analog switch from Analog Devices, fabricated on an enhanced LC2MOS process. It supports a maximum supply rating of 44 V and an analog signal range of ±15 V. 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 are characterized by a maximum turn-on time (tON) of 600 ns and turn-off time (tOFF) of 450 ns. The device operates within a temperature range of −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS technology provides high breakdown voltage and extended analog signal handling capability up to ±15 V.
• Break-before-make switching action prevents short circuits when multiple outputs are tied together in multiplexer applications.
• Low leakage currents and low charge injection minimize transients and errors in high-precision circuits.
• TTL/CMOS compatible digital control logic allows for flexible interface with standard logic families.

Analog Switches, Multiplexers, Demultiplexers Applications

• Multiplexer systems requiring break-before-make switching to avoid output contention.
• High-precision measurement circuits where low leakage and minimal charge injection are critical.
• Signal routing in instrumentation and data acquisition systems.
• Applications requiring single or dual supply operation with unipolar or bipolar signals.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as REEL variants indicate tape-and-reel packaging compared to tube options. Ensure the component meets RoHS compliance requirements if specified for the project. Confirm that the SOIC-16 package dimensions align with the target PCB footprint. Check for any lead-free status indicators in the final part marking.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG211AKR-REEL when inverted digital control logic is required, distinguishing it from the pin-compatible ADG212A which uses non-inverted logic. Consider the 115 Ω maximum on-resistance for signal integrity in low-voltage applications. Evaluate the ±15 V signal range against the system's maximum input levels. The SOIC-16 package is suitable for surface-mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG211A/ADG212A family of monolithic CMOS switches. It is designed as a direct replacement for legacy DG211 devices, offering improved performance through the LC2MOS process. The family includes various package options such as PDIP, SOIC, and PLCC, catering to different manufacturing and thermal requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG211AKR-REEL is pin-compatible with the Maxim Integrated DG211 series. When substituting, verify that the control logic polarity matches the design intent, as the ADG211A uses inverted logic relative to some older counterparts. Ensure the replacement part supports the required analog signal voltage range and operating temperature conditions.
