ADG212AKN

ADG212AKN Description

The ADG212AKN 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 package, this obsolete but robust IC features 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 bipolar or unipolar systems. With fast switching times (600ns Ton, 450ns Toff) and low charge injection (20pC), it minimizes distortion in high-speed or sensitive analog circuits.

ADG212AKN Features

• Low On-Resistance: 115Ω max with tight channel-to-channel matching (ΔRon 5.75Ω), reducing signal attenuation.
• Low Leakage & Capacitance: 5nA max off-state leakage and 5pF channel capacitance for high isolation.
• Wide Supply Range: Compatible with ±15V dual or +15V single supplies, ideal for mixed-voltage systems.
• Fast Switching: 600ns/450ns (Ton/Toff) enables rapid signal routing.
• Low Charge Injection: 20pC ensures minimal glitch in precision sampling applications.
• Durable Packaging: Through-hole 16-DIP with MSL 1 (Unlimited) moisture sensitivity, suitable for industrial environments.

ADG212AKN Applications

• Test & Measurement Equipment: Signal multiplexing in data acquisition systems.
• Audio/Video Routing: Low-distortion switching in professional AV systems.
• Medical Instrumentation: High-reliability signal paths in diagnostic devices.
• Industrial Control Systems: Robust performance in harsh environments.
• Battery-Powered Devices: Low leakage preserves energy efficiency.

Conclusion of ADG212AKN

The ADG212AKN excels in applications requiring low noise, fast switching, and high signal fidelity. While obsolete, its low on-resistance, minimal leakage, and dual-supply flexibility make it a preferred choice for legacy designs or replacements in critical systems. Engineers value its reliability in precision analog routing, though modern alternatives may offer enhanced integration. Ideal for industrial, medical, and test equipment where performance outweighs obsolescence concerns.
