ADG211AKNZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG211AKNZ is a monolithic CMOS device comprising four independently selectable single-pole single-throw (SPST) switches. Fabricated on an enhanced LC2MOS process, it supports a maximum supply rating of 44 V and an analog signal range of ±15 V. The device features a maximum on-resistance (RON) of 115 Ω and typical leakage currents of 0.5 nA. It operates within an extended temperature range of −40°C to +85°C and utilizes TTL/CMOS compatible digital inputs. The component is housed in a 16-lead plastic dual in-line package (PDIP).

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process enables high breakdown voltage and increased analog signal handling capability.
• Inherent break-before-make switching action minimizes transients when driving multiple switches simultaneously.
• Low charge injection design reduces output transients during digital input switching events.

Analog Switches, Multiplexers, Demultiplexers Applications

• Multiplexer applications requiring tied outputs with minimal leakage errors.
• High precision circuits necessitating low leakage current characteristics.
• Signal routing for unipolar or bipolar analog signals within specified voltage ranges.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment. Cross-reference pin configurations if substituting from legacy components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring robust signal handling up to ±15 V with low on-resistance. Consider the PDIP package constraints for board layout and thermal dissipation. Verify that the logic supply voltage aligns with the system's digital interface requirements for proper TTL/CMOS compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG211AKNZ belongs to the ADG211A/ADG212A family of quad SPST switches. It serves as a direct pin-compatible replacement for the DG211 series, offering improved signal range and lower leakage while maintaining similar form factors. This lineage ensures backward compatibility for existing designs upgrading to enhanced performance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG211AKNZ is explicitly documented as pin-compatible with the DG211 series devices. Designers replacing older components should verify that the legacy part's absolute maximum ratings are not exceeded by the new device's operational parameters.
