The MAX323CSA from Maxim Integrated is a precision, dual-voltage, SPST (Single-Pole Single-Throw) analog switch designed to provide high-performance switching capabilities for a wide range of applications. This analog switch is characterized by its low power consumption and high-speed operation, which makes it an excellent choice for portable and battery-powered devices.

Key Features

• Low Voltage Operation: The device operates from a single +2V to +12V supply or from dual ±2V to ±6V supplies.
• Low On-Resistance: It features a low on-resistance of 100Ω max, which is matched between channels to within 5Ω max and remains flat over the specified signal range (0.3Ω max).
• High-Speed Switching: The switch conducts signals within nanoseconds, ensuring rapid response times suitable for high-frequency applications.
• Low Power Consumption: The MAX323CSA is optimized for low power consumption, with a quiescent current of just 1µA max, which helps to extend battery life in portable devices.
• ESD Protection: It features enhanced electrostatic discharge (ESD) protection, with ±15kV Human Body Model (HBM) protection on the switch input, which safeguards the device from static electricity and other transient voltage events.
• Wide Operating Temperature Range: The device is designed to operate over the extended industrial temperature range of -40°C to +85°C, making it suitable for harsh environments.
