MAX352CSE Description

The MAX352CSE is a surface-mount, single-pole single-throw (SPST) analog switch designed by Analog Devices Inc./Maxim Integrated. This device is part of the MAX352 family and is housed in a 16SOIC package. It features four independent SPST-NO (normally open) switches, each with a maximum on-state resistance (Ron) of 35 ohms. The MAX352CSE operates over a wide supply voltage range, supporting both single and dual supply configurations. The single supply voltage range is from 10V to 30V, while the dual supply voltage range is ±4.5V to ±20V. This flexibility makes it suitable for a variety of applications requiring different power supply configurations.

MAX352CSE Features

• Low Leakage Current: The MAX352CSE boasts a maximum leakage current (IS(off)) of 250pA, ensuring minimal power consumption and maintaining signal integrity when the switch is off.
• High Channel Matching: With a maximum channel-to-channel matching (ΔRon) of 2 ohms, the MAX352CSE ensures consistent performance across all four channels, making it ideal for applications requiring precise signal routing.
• Low On-State Resistance: The maximum on-state resistance (Ron) of 35 ohms ensures minimal signal attenuation and power loss when the switch is on.
• Low Charge Injection: The device has a low charge injection of 5pC, which is crucial for maintaining signal fidelity in sensitive analog circuits.
• Fast Switching Times: The MAX352CSE offers fast turn-on (Ton) and turn-off (Toff) times of 175ns and 145ns, respectively, enabling rapid signal switching without significant delays.
• Wide Operating Temperature Range: The operating temperature range of 0°C to 70°C (TA) makes the MAX352CSE suitable for a broad range of industrial and consumer applications.
• Moisture Sensitivity Level (MSL) 1: The MSL rating of 1 (unlimited) indicates that the device is not moisture-sensitive, simplifying handling and storage processes.
• Compliance: The MAX352CSE is REACH unaffected, ensuring compliance with environmental and safety regulations.
