This new IC chip connects with a Four-channel temperature sensor, integrates converters, amplifiers and compensation sensors for high accuracy temperature measurement.
Microchip Technology has launched a new Integrated Circuit (IC) called MCP9604, for accurate measurement of heat, from thermal sensors. It’s a four-channel thermocouple conditioning chip, works over I2C and measures temperature with accuracy of up to ±1.5°C.
It is built for production-line monitoring in industries such as chemical processing, food manufacturing, medical devices, HVAC systems, and cold storage where precise temperature control is critical.
Thermocouples are the sensors for measuring temperature, but it needs separate parts like amplifiers, converters and compensation sensors, adding complexity to the whole system. The new IC has combined these elements to simplify design and reduce errors.
The IC supports four thermocouple inputs at once. It uses detailed NIST temperature equations instead of simple linear methods, which allows it to achieve higher accuracy. With a K-type heat sensor, it can apply ninth-order calculations to give more reliable results.
All functions needed for measuring temperature are in the IC like, analogue-to-digital converters, cold junction compensation, amplifiers and the calculation engine. Because these are integrated, engineers can avoid using as many as 15 external parts.
It also cuts down the time and cost for testing and calibration that normally need to be done for each system built with discrete components.
The device can work with eight common types of thermocouples, including K-type, which can measure from -200°C up to +1372°C. This wide range makes it suitable for both cryogenic and high-heat applications. Its I2C interface means it can connect directly with microcontrollers and digital control systems, which simplifies integration into industrial setups.
