MAX309CSE - Precision, 8-Channel/Dual 4-Channel, Low-Voltage, CMOS Analog Multiplexers

The MAX309CSE from Maxim Integrated is a highly versatile and precise analog multiplexer that offers exceptional performance for signal routing in various electronic applications. Designed with cutting-edge CMOS technology, this component is ideal for configurations that require low-voltage operations, making it suitable for battery-powered devices and portable equipment.

This robust multiplexer comes in two configurations: as an 8-channel single-ended device or as a dual 4-channel differential device, providing flexibility for designers to choose the best fitting model for their specific requirements. The MAX309CSE operates with a single supply voltage ranging from +4.5V to +30V, or a dual supply from ±4.5V to ±20V, ensuring compatibility with a wide range of systems.

The device boasts a low on-resistance of less than 100 ohms, which is matched between channels to within 5 ohms and remains flat over the specified analog signal range. This ensures minimal signal distortion and excellent linearity, making the MAX309CSE an ideal choice for precision applications such as data acquisition systems, test equipment, and audio signal routing.

One of the key features of the MAX309CSE is its ESD protection, which exceeds 2000V per Method 3015.7 of MIL-STD-883C. This level of protection ensures the device's reliability and longevity in harsh environments. Additionally, the multiplexer includes break-before-make switching, which prevents momentary shorting when switching between channels.

Other notable features include the low crosstalk and off-isolation, which further contribute to the device's signal integrity. The MAX309CSE also offers TTL/CMOS-compatible digital inputs, making it easy to interface with a wide range of logic controllers and microprocessors.

Available in a 16-pin narrow SO package, the MAX309CSE is designed for space-saving in PCB designs, without compromising on functionality or performance. Whether for industrial control systems, communication devices, or medical equipment, the MAX309CSE is a reliable and efficient solution for your analog multiplexing needs.
