The MAX323CSA+ is a precision, dual-voltage, SPST (Single-Pole Single-Throw) analog switch from Maxim Integrated, designed to provide superior switching performance for a variety of applications. This component is part of Maxim's commitment to delivering high-quality, reliable integrated circuits that meet the demanding requirements of modern electronic systems.

Key Features

• Low Voltage Operation: The MAX323CSA+ operates at a single +2V to +12V supply or at ±2V to ±6V dual supplies, making it versatile for both digital and analog signal switching.
• Low On-Resistance: It features a low on-resistance (R<sub>ON) of 100Ω max, ensuring minimal signal distortion and power loss during operation.
• High Accuracy: The device offers high accuracy with a guaranteed R<sub>ON match between channels of 5Ω max and R<sub>ON flatness of 4Ω max, which is critical for precision applications.
• Fast Switching Speeds: The switch transition times (t<sub>ON/t<sub>OFF) are exceptionally fast, typically 175ns/145ns, thus suitable for high-speed signal routing.
• Low Power Consumption: With a low power consumption, the MAX323CSA+ is ideal for power-sensitive applications, offering a quiescent current of only 1µA max.
• ESD Protection: It includes enhanced ESD protection, with ±2000V Human Body Model (HBM) protection on the switch inputs, minimizing the risk of damage during handling and operation.
