MAX31855KASA+T +BOM

Cold-Junction Compensated Thermocouple-to-Digital Converter

MAX31855KASA+T Information

Description

Here's a concise introduction to the MAX31855KASA+T: The MAX31855KASA+T is a digital serial temperature sensor from Analog Devices, designed for thermocouple interfaces in industrial control systems, HVAC equipment, and scientific instruments. This 8-pin SOIC device features a high-resolution (14-bit) converter with 0.25°C resolution, integrated cold-junction compensation, and detection of thermocouple shorts to ground or VCC, as well as open thermocouples. The sensor is SPI-compatible and interfaces easily with most microcontrollers. With its compact package and low power consumption, the MAX31855KASA+T simplifies temperature measurement applications while providing accurate and reliable results.

Features

According to the product information, the features of the MAX31855KASA+T are:

  • Integration reduces design time and lowers system cost
  • 14-bit, 0.25°C resolution converter
  • Integrated cold-junction compensation
  • Versions available for most common thermocouple types: K-, J-, N-, T-, S-, R-, and E-Type
  • Detects thermocouple shorts to GND or VCC
  • Detects open thermocouple
  • Interfaces to most microcontrollers with a simple SPI-compatible interface (read-only)

These features make the MAX31855KASA+T suitable for temperature measurement applications, particularly in thermocouple interfaces, and are commonly employed in industrial control systems, HVAC equipment, and scientific instruments.
