MAX355CWE

MAX355CWE Description

The MAX355CWE from Analog Devices Inc./Maxim Integrated is a high-performance, dual 4:1 SP4T (Single Pole 4 Throw) analog switch/multiplexer designed for precision signal routing in demanding applications. Housed in a 16-SOIC package, this IC offers low leakage current (500pA max) and moderate on-resistance (350Ω max), making it suitable for low-power and high-accuracy systems. It operates over a wide voltage range (±4.5V to ±18V dual supply or 4.5V to 36V single supply) and features excellent channel-to-channel matching (ΔRon = 7Ω). Although marked as Obsolete, its robust design ensures reliability in legacy or long-lifecycle systems.

MAX355CWE Features

• Low Leakage Current: 500pA max ensures minimal signal distortion in high-impedance circuits.
• Fast Switching: Ton/Toff = 250ns/200ns enables rapid signal routing.
• Low Charge Injection: 80pC reduces glitches in sensitive analog applications.
• Low Capacitance: CS(off) = 1.6pF, CD(off) = 5pF minimizes crosstalk and signal degradation.
• Wide Voltage Range: Supports ±18V dual or 36V single supply for versatile compatibility.
• Dual 4:1 Configuration: Two independent SP4T switches in one package save board space.
• REACH Unaffected: Compliant with environmental regulations for industrial use.

MAX355CWE Applications

• Test & Measurement Equipment: Precision signal routing in data acquisition systems.
• Medical Instrumentation: Low-leakage switching for ECG or sensor interfaces.
• Audio/Video Switching: High-fidelity signal multiplexing in professional AV systems.
• Industrial Control Systems: Reliable operation in harsh environments (0°C to 70°C).
• Battery-Powered Devices: Low power consumption extends battery life.

Conclusion of MAX355CWE

The MAX355CWE excels in applications requiring low leakage, fast switching, and high voltage tolerance. Its dual SP4T architecture and robust performance make it ideal for precision analog systems, though designers should note its obsolete status and plan for alternatives in new designs. For legacy systems or niche requirements, it remains a dependable choice from Maxim Integrated's proven portfolio.
