ADG201HSJN

ADG201HSJN Description

The ADG201HSJN 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 (Through Hole) package, this obsolete but robust component offers low leakage current (1nA max) and a moderate on-state resistance (50Ω max), making it suitable for both low-voltage and dual-supply systems (±13.5V to 16.5V or single-supply 10.8V to 16.5V). Its 1:1 multiplexer/demultiplexer circuit architecture ensures minimal signal distortion, while the low charge injection (10pC) and balanced channel capacitance (10pF CS/CD off) enhance signal integrity.

ADG201HSJN Features

• Low Leakage Current: Max 1nA ensures minimal power loss in high-impedance circuits.
• Dual/ Single-Supply Operation: Supports ±16.5V or +16.5V, offering flexibility in system design.
• Fast Switching: 75ns turn-on/off time for rapid signal routing.
• Low On-Resistance: 50Ω max with tight channel matching (ΔRon 1.5Ω), reducing signal attenuation.
• High Reliability: MSL 1 (Unlimited) moisture sensitivity and EAR99/ HTSUS 8542.39.0001 compliance for industrial use.
• Low Charge Injection: 10pC minimizes glitches in precision sampling applications.

ADG201HSJN Applications

• Test & Measurement Equipment: Ideal for automated test systems due to low distortion and fast switching.
• Data Acquisition Systems: Ensures accurate signal routing in multi-channel ADCs/DACs.
• Audio/Video Switching: Low capacitance and leakage preserve signal fidelity in AV multiplexing.
• Industrial Control Systems: Robust performance in harsh environments with wide supply ranges.
• Medical Instrumentation: Reliable for low-noise signal paths in diagnostic devices.

Conclusion of ADG201HSJN

The ADG201HSJN excels in applications demanding low noise, fast switching, and high precision, despite its obsolete status. Its dual/single-supply versatility, low leakage, and tight channel matching make it a preferred choice for legacy designs or systems requiring proven reliability. While newer alternatives exist, this device remains a benchmark for low-distortion analog switching in professional electronics.
