UNIVERSAL INPUT REFERENCE DESIGN PROVIDES ACCURACY AND FLEXIBILITY FOR INDUSTRIAL SENSORS

Achieve 24-bit signal chain performance with isolated power and data using Maxim Integrated's Micro PLC MAXREFDES67#.

San Jose, CA—November 16, 2015—Industrial automation engineers can now achieve highly accurate measurements for their system designs with the MAXREFDES67# analog front end (AFE) universal input Micro PLC reference design from Maxim Integrated Products, Inc. (NASDAQ: MXIM).

As high-resolution systems move to higher bit counts, they become more sensitive to noise, making such systems difficult to build and maintain accuracy. MAXREFDES67# is a unique 24-bit AFE reference design that overcomes this challenge. Capable of accepting four different signals, the MAXREFDES67# universal analog input requires no jumpers and is 100% software configurable.

To meet Industry 4.0 requirements, Maxim partnered with Wurth Electronics Midcom to customize a power isolation transformer that is energy efficient and compact enough to fit in Maxim's credit-card sized Micro PLC form factor.

Key Advantages

• High accuracy: effective resolution up to 22.3 bits with temperature error as low as ±0.1% across a range of -40°C to 150°C
• Ease of use: Beyond-the-Rails signal chain reduces board space, component count, and cost
• Flexible: universal input accepts four different signals—voltage, current, resistance temperature detector (RTD), and thermocouple (TC)

Commentary

• "MAXREFDES67 is by far the highest performance analog reference design that Maxim has ever built," said David Andeen, Director of Reference Designs at Maxim Integrated. "It also features a complete Beyond the Rails signal chain, enabling the entire system to process inputs in excess of the bias voltages for each component."

Availability

• The MAXREFDES67# reference design is available for $99 at Maxim's website and select franchised distributors. Hardware and firmware design files, as well as test data, are provided free and available online.
