World’s First Integrated Thermocouple Electromotive Force to Degrees Celsius Converter From Microchip Saves Design Effort, Space and Cost

Industry’s First Converter IC to Integrate Precision Instrumentation, Temperature Sensor and High-Res ADC, Along With Math Engine That Supports Most Thermpcouple Types

CHANDLER, Ariz., Aug. 31, 2015 — Microchip Technology Inc. today announced the MCP9600—the world’s first thermocouple-conditioning integrated circuit to combine precision instrumentation, a precision temperature sensor and a precision, high-resolution analog-to-digital converter (ADC), in addition to a math engine preprogrammed with the firmware to support a broad range of standard thermocouple types (K, J, T, N, S, E, B and R). Thermocouples are one of the most ubiquitous temperature-measurement devices, due to their robustness and accuracy in harsh, high-temperature environments, and their ability to measure temperature over an extremely wide range. The MCP9600 simplifies thermocouple designs by integrating a number of discrete devices into one chip, which also lowers board area, cost and power consumption.

Thermocouples are widely used to measure temperature by the designers of industrial, consumer, automotive/aerospace and petrochemical applications, among others. The MCP9600 pro18171590202_370bffb522_ovides them with the world’s first plug-and-play solution for creating thermocouple-based designs, because it eliminates the design expertise required for a discrete implementation, such as firmware development using an MCU’s math engine. Designers no longer have to create precision instrumentation circuitry to accurately measure a thermocouple’s microvolt-level signals, nor do they have to design ADC circuitry for precise temperature calculations. With the MCP9600’s integrated cold-junction compensation, calculating the “Hot” junction temperature of a thermocouple doesn’t necessitate thermal design expertise to precisely measure the reference temperature of the thermocouple’s “Cold” junction.

Other features of the MCP9600 include a temperature-data digital filter, which minimizes the effects of temperature fluctuations, system noise and electromagnetic interference. Its shutdown modes reduce overall system power consumption, while its four user-programmable temperature-alert outputs reduce the system microcontroller’s overhead and code space, while further simplifying designs.
Finally, the MCP9600 comes in a 5×5 mm, 20-lead mQFN package, which further reduces board area and manufacturing cost.

“The MCP9600 is the only system-on-a-chip thermocouple-conditioning IC on the market,” said Bryan J. Liddiard, marketing vice president of Microchip’s Analog and Interface Products Division. “It offers customers a fully integrated, plug-and-play solution for a non-trivial application, saving development time and resources.”
