Maxim Integrated's MAX397CAI+ Multiplexer

The MAX397CAI+ from Maxim Integrated is a high-performance, 16-channel, single-ended analog multiplexer that operates from a single supply ranging from +4.5V to +36V or dual supplies of ±4.5V to ±20V. This versatile multiplexer is designed to handle a variety of signal applications, making it an ideal choice for data acquisition systems, process controls, and instrumentation.

Featuring a low on-resistance of 100 ohms max, which is matched between channels to within 6 ohms max and flat (6 ohms max) over the specified signal range, the MAX397CAI+ ensures excellent signal integrity with minimal attenuation or distortion. The device also boasts a low leakage current of only 2.5nA at +25°C, which further enhances its precision and reliability in sensitive analog circuits.

The MAX397CAI+ can be controlled via a 4-bit digital interface, which allows users to select any one of the 16 single-ended channels to connect to the common output. The digital inputs are compatible with TTL and CMOS logic levels, making integration with microcontrollers and digital systems seamless. For added flexibility, the device features an inhibit input that opens all channels when activated, effectively disconnecting any signal paths through the multiplexer.

With its extended operating temperature range of -40°C to +85°C, the MAX397CAI+ is built to perform reliably in harsh environments. This robustness, combined with its ESD protection greater than 2000V per Method 3015.7, ensures that the MAX397CAI+ can withstand the rigors of industrial applications.

The device is packaged in a 28-pin SSOP, which provides a compact footprint while still offering easy integration into a wide range of electronic systems. Whether used in data acquisition, process control, or other analog signal routing applications, the MAX397CAI+ from Maxim Integrated is a versatile and reliable choice for designers looking to maximize performance and minimize board space.

For those looking to implement high-quality signal routing with minimal signal loss and high precision, the MAX397CAI+ offers a compelling solution that combines performance with robustness in a single, compact package.
