ADG211AKN

ADG211AKN Description

The ADG211AKN from Analog Devices Inc. is a high-performance, 4-channel SPST (Single-Pole Single-Throw) analog switch designed for precision signal routing in demanding applications. Housed in a 16-pin DIP (Dual Inline Package), this obsolete but robust IC offers low on-state resistance (115Ω max) and minimal leakage current (5nA max), ensuring high signal integrity. It supports dual (±15V) or single (+15V) supply voltages, making it versatile for mixed-voltage systems. With fast switching times (600ns Ton, 450ns Toff) and low charge injection (20pC), it minimizes distortion in high-speed or sensitive analog circuits.

ADG211AKN Features

• Low On-Resistance: 115Ω max reduces signal attenuation.
• Low Leakage: 5nA max ensures minimal power loss.
• Fast Switching: 600ns/450ns (Ton/Toff) for dynamic signal routing.
• Dual/Single Supply: Compatible with ±15V or +15V operation.
• Low Charge Injection: 20pC minimizes glitches in precision systems.
• Channel Matching: ΔRon of 5.75Ω for consistent performance across channels.
• Low Capacitance: 5pF (CS/CD off) reduces crosstalk in high-frequency applications.

ADG211AKN Applications

• Test & Measurement Equipment: Precision signal switching in oscilloscopes or data acquisition systems.
• Audio/Video Routing: Low-distortion signal paths in professional AV systems.
• Industrial Control Systems: Reliable multiplexing for sensors or actuators.
• Medical Instrumentation: High-accuracy signal handling in diagnostic devices.
• Battery-Powered Devices: Low leakage conserves energy in portable electronics.

Conclusion of ADG211AKN

The ADG211AKN excels in applications demanding low distortion, fast switching, and high signal fidelity. While obsolete, its low on-resistance, dual-supply flexibility, and robust performance make it a legacy choice for precision analog routing. Ideal for industrial, medical, and test systems, it balances speed and accuracy where signal integrity is critical. Engineers seeking replacements should consider newer ADG-series variants with enhanced specs.
