The MAX309CUE from Maxim Integrated is a high-performance, precision analog multiplexer (mux) designed to cater to a broad range of applications including data acquisition systems, process controls, and instrumentation. This device is a single, 8-channel multiplexer that allows multiple analog signals to be routed to a single output, making it a versatile choice for systems that require multiple input channels but have limited ADCs (analog-to-digital converters).

Key Features

• Channel Configuration: The MAX309CUE features an 8-to-1 single-ended channel configuration, providing the flexibility to handle eight different analog signals through one multiplexer.
• Low On-Resistance: With an on-resistance of just 100 ohms, this multiplexer ensures minimal signal attenuation, which is crucial for maintaining signal integrity in precision applications.
• Single-Supply Operation: It operates on a single supply voltage ranging from +4.5V to +30V, or a dual supply of ±4.5V to ±20V, accommodating a wide array of system requirements.
• Low Crosstalk and Off Leakage: The device boasts excellent isolation properties with low crosstalk between channels and minimal off leakage current, ensuring accurate and reliable signal switching.
• ESD Protection: The inputs and outputs are protected against electrostatic discharge (ESD) events, enhancing the robustness of the device in harsh environments.
• Break-Before-Make Switching: This feature prevents momentary shorting of channels during switching, which is critical for preventing damage to sensitive components and maintaining system integrity.
