Integrated system designs save power and time

Fully tested subsystems, complete with schematics, layout files and firmware, the Carmel, Monterey, and Fremont industrial reference designs are available for immediate use and customization. Each reference design integrates multiple functions to provide a highly accurate solution for an automated factory task. Each board ensures rapid prototyping, early software development, and speed of design.

Carmel:

Ideal for programmable logic controllers and distributed control systems, the Carmel (MAXREFDES18#) subsystem provides a high-accuracy, low-noise analog output.

• High performance: accurate output from high voltages down to true zero,
• Integrated error reporting: detection of short circuit, open circuit, brown-out, and overtemperature conditions,
• Flexibility: provides both current and voltage outputs, including bipolar signals of -20mA to 20mA and -10V to 10V.

Monterey:

Ideal for distributed industrial sensor systems, the Monterey (MAXREFDES15#) subsystem is a high-accuracy, industrial loop-powered sensor transmitter that converts a standard temperature sensor input (RTD PT1000) to a 4–20mA signal that is immune to noise and is constant over long distances.

• Ultra-low power: system current consumption is less than 2.1mA (a 40% improvement compared to the industry standard),
• High accuracy: supports 0.1% system accuracy over a full process variable-input range,
• Ease of design: all design files are included for rapid prototyping.

Fremont:

Ideal for low-voltage output sensors, and process control and medical applications, the Fremont (MAXREFDES6#) subsystem is a low-power analog front-end that accepts inputs of 0mV to 100mV.

• Low power: less than 300mW typical power consumption,
• Reduced time to market: fast prototyping with all necessary design files included.
• Simplicity: single-ended system eliminates the need to convert to differential signals.
