Maxim Integrated MAX337CAI+ Analog Multiplexer

The Maxim Integrated MAX337CAI+ is a precision, 16-channel analog multiplexer that offers high-performance signal routing for a wide range of applications. This versatile component is designed to work with dual supplies ranging from ±4.5V to ±20V or a single supply between +9V and +36V, making it suitable for various operating conditions.

Featuring low on-resistance (100Ω max) and low charge injection (10pC max), the MAX337CAI+ ensures signal integrity, minimizing the impact on the signals being switched. Its on-resistance is matched between channels to within 4Ω max and remains flat (9Ω max) over the specified signal range, providing consistent performance across all channels.

The MAX337CAI+ is equipped with an inhibit input to simultaneously open all signal paths, offering a convenient way to disconnect all channels with a single control line. This feature can be particularly useful in power-down modes or when maintenance of the signal paths is required without powering down the entire system.

With a transition time of 250ns max and an off-leakage current of only 0.5nA at +25°C, the MAX337CAI+ is designed for swift and precise signal switching with minimal leakage, making it ideal for low-power and high-speed applications. Its ESD protection exceeds 2000V per Method 3015.7, ensuring robustness and reliability in harsh environments.

The device is offered in a 28-pin SSOP package, providing a compact solution that is easy to integrate into space-constrained designs. The MAX337CAI+ is an excellent choice for data acquisition systems, communication systems, test equipment, and any application that requires accurate and efficient routing of multiple analog signals.
