The MAX6675 performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI-compatible, read-only format. The converter has a temperature resolution of 0.25°C, with a maximum readable temperature of +1024°C, and a thermocouple accuracy of 8 LSB over the temperature range of 0°C to +700°C. The MAX6675 comes in a compact 8-pin SO package. The MAX6675 is a precision thermocouple-to-digital converter with a built-in 12-bit analog-to-digital converter (ADC). It also includes cold-junction compensation sensing and correction, a digital controller, an SPI-compatible interface, and associated control logic. The MAX6675 is designed to work with an external microcontroller (μC) or other intelligent devices, making it suitable for applications such as temperature regulation, process control, or monitoring.
