Thermocouple conditioning IC

14 October 2015 Analogue, Mixed Signal, LSI

Microchip rolled out the MCP9600, the world’s first thermocouple conditioning IC to combine precision instrumentation, a precision temperature sensor and a precision, high-resolution analog-to-digital converter (ADC), in addition to a maths engine pre-programmed with the firmware to support a broad range of standard thermocouple types: K, J, T, N, S, E, B and R.

With the device’s integrated cold-junction compensation, calculating the ‘Hot’ junction temperature of a thermocouple does not 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 minimises 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.

The chip comes in a 5 x 5 mm, 20-lead mQFN package, and is supported by an optional evaluation board.
