Maxim Integrated's MAX309CPE+: High-Precision, 8-Channel/Dual 4-Channel, CMOS Analog Multiplexers

The MAX309CPE+ from Maxim Integrated is a versatile and high-performance analog multiplexer that offers a combination of precision and flexibility, making it an ideal choice for a variety of demanding applications. This device features an 8-channel single-ended configuration or a dual 4-channel differential configuration, providing designers with the ability to select the mode that best fits their circuit requirements.

Constructed using Maxim's proprietary silicon-gate CMOS process, the MAX309CPE+ offers excellent digital logic-level characteristics, allowing it to interface with a wide range of supply voltages and logic families. This makes it not only easy to use but also compatible with various microprocessors and digital systems.

The multiplexer’s low on-resistance (100 ohms max) and low charge injection (5pC max) ensure that signals are switched with minimal distortion and high integrity, which is critical for precision analog applications. Additionally, the device boasts low crosstalk and off-isolation, further contributing to the accuracy and quality of signal routing.

With a single digital select input, users can control multiple signal paths, saving on board space and reducing complexity in the design. The MAX309CPE+ operates over a wide voltage range of ±4.5V to ±20V or a single supply of +9V to +36V, providing flexibility in various power environments.

Its robust design includes electrostatic discharge (ESD) protection circuitry, which guards the device against inadvertent static discharges that can be harmful to electronic components. The MAX309CPE+ is available in a 16-pin plastic DIP package, which is widely accepted in the industry and suitable for through-hole mounting, simplifying the assembly process.

Whether used in data acquisition systems, test equipment, communication systems, or other analog applications, the MAX309CPE+ delivers reliable performance with Maxim Integrated's hallmark quality. Its combination of high precision, low power consumption, and ease of use makes it a valuable component in any designer's toolkit.
