MAX351EPE

MAX351EPE Description

The MAX351EPE is a high-performance, single-pole single-throw (SPST) switch IC designed for a variety of applications requiring reliable and efficient signal routing. Manufactured by Analog Devices Inc./Maxim Integrated, this through-hole mounted device is housed in a tube package and features a base product number of MAX351. Despite being marked as obsolete, the MAX351EPE remains a robust choice for specific applications due to its unique combination of low leakage current, wide supply voltage range, and excellent on-state resistance.

MAX351EPE Features

• Low Leakage Current: The MAX351EPE boasts a maximum leakage current (IS(off)) of 250pA, ensuring minimal power loss and high signal integrity when the switch is off.
• Wide Supply Voltage Range: It operates from a dual supply voltage of ±4.5V to ±20V or a single supply voltage of 10V to 30V, providing flexibility in various power configurations.
• High Channel-to-Channel Matching: With a maximum channel-to-channel matching (ΔRon) of 2Ohm, the MAX351EPE ensures consistent performance across multiple channels.
• Low On-State Resistance: The maximum on-state resistance (Ron) of 35Ohm guarantees minimal signal attenuation and power dissipation when the switch is on.
• Low Charge Injection: At 5pC, the charge injection is minimized, which is crucial for maintaining signal fidelity in sensitive applications.
• Fast Switching Times: The switch time (Ton, Toff) is maximized at 175ns and 145ns respectively, enabling rapid signal switching without significant delays.
• Low Channel Capacitance: Both CS(off) and CD(off) are rated at 9pF, reducing the risk of signal distortion and ensuring high-frequency performance.
• Compliance and Packaging: The MAX351EPE is REACH unaffected and has a moisture sensitivity level (MSL) of 1, making it suitable for a wide range of environmental conditions. It is also available in a tube package, which is ideal for bulk handling and automated assembly processes.
