MAX6675ISA

Sensor And Detector Interfaces Overview

The MAX6675ISA is a cold-junction-compensated K-type thermocouple-to-digital converter housed in an 8-pin SO package. It digitizes the thermocouple signal with 12-bit resolution and 0.25°C resolution, supporting readings up to +1024°C. The device operates on a supply voltage of 3.0V to 5.5V with a typical current consumption of 1.5mA. It features an SPI-compatible serial interface for read-only data output. Thermocouple accuracy is specified at 8 LSBs within the 0°C to +700°C range. The operating temperature range extends from -20°C to +85°C.
