DG201ACJ Description

The DG201ACJ is an obsolete SPST-NC (Single-Pole Single-Throw, Normally Closed) analog switch from Analog Devices Inc./Maxim Integrated, designed for precision signal routing in demanding applications. Housed in a 16-pin DIP (Through Hole) package, this device integrates four independent switches with a low on-state resistance (200Ω max) and minimal leakage current (5nA max). It operates over a dual-supply voltage range of ±4.5V to ±18V, making it suitable for both low and high-voltage systems. With fast switching times (600ns Ton, 450ns Toff) and low charge injection (20pC), it ensures minimal signal distortion in high-speed applications.

DG201ACJ Features

• Low Leakage & High Isolation: 5nA max leakage current and 5pF channel capacitance ensure minimal signal bleed-through.
• Wide Voltage Range: Supports ±4.5V to ±18V dual supplies, ideal for mixed-voltage systems.
• Fast Switching: 600ns/450ns (Ton/Toff) enables rapid signal routing.
• Low Charge Injection: 20pC reduces glitches in precision analog circuits.
• Robust Packaging: 16-DIP tube packaging with MSL 1 (Unlimited) moisture sensitivity, suitable for industrial environments.
• REACH Unaffected: Compliant with environmental regulations.

DG201ACJ Applications

• Test & Measurement Equipment: Precision signal switching in data acquisition systems.
• Audio/Video Routing: Low-distortion signal multiplexing in professional AV systems.
• Battery-Powered Systems: Efficient signal management in portable devices due to low leakage.
• Industrial Control Systems: Reliable operation in 0°C to 70°C environments.
• Medical Instrumentation: High-accuracy switching for diagnostic equipment.

Conclusion of DG201ACJ

The DG201ACJ excels in applications requiring low noise, fast switching, and high voltage tolerance. While obsolete, its low on-resistance, minimal charge injection, and robust DIP packaging make it a reliable choice for legacy designs or systems requiring proven performance. Engineers working on precision analog routing, industrial controls, or portable instrumentation may find this IC particularly valuable despite its discontinued status.
