MAX6675ISA+T

Sensor And Detector Interfaces Overview

The MAX6675ISA+T is a cold-junction-compensated K-type thermocouple-to-digital converter manufactured by Analog Devices Inc. (Maxim Integrated). It features a built-in 12-bit analog-to-digital converter and operates on a supply voltage ranging from 3.0 V to 5.5 V with a typical supply current of 0.7 mA. The device provides a resolution of 0.25°C and supports temperature readings up to +1024°C. It utilizes an SPI-compatible serial interface for data output and includes open thermocouple detection capabilities. The component is housed in an 8-pin SO package and functions within an operating temperature range of -20°C to +85°C.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm RoHS compliance status, as indicated by the plus sign. Confirm that the SO-8 package dimensions match your PCB footprint requirements. Ensure the input voltage levels align with your system's power supply specifications before integration.

Sensor And Detector Interfaces Selection Notes

Select this component when interfacing directly with type-K thermocouples requiring integrated signal conditioning. The internal cold-junction compensation eliminates the need for external reference sensors. Verify that the required measurement range does not exceed the specified limits and that the SPI interface timing meets your microcontroller's clock frequency constraints.
