MAX6675ISA+TAnalog DevicesThermocouple converter · SOIC-8MAX6675ISA+T is an Analog Devices (Maxim) cold-junction-compensated K-thermocouple-to-digital converter — 12-bit resolution, 0.25 °C per LSB, measuring 0 to +1024 °C, SPI-compatible read-only interface, in SOIC-8, 3 to 5.5 V supply, operating -20 to +85 °C. One chip replacing the thermocouple amplifier, ADC, cold-junction sensor and linearization table is the selection point: a direct digital temperature reading from a type-K probe with open-thermocouple detection, for industrial ovens, appliances and HVAC. Selection advice: this is type-K only and reads 0 °C to +1024 °C — it cannot measure below 0 °C or other thermocouple types, so for sub-zero or multi-type designs look at the MAX31855 family instead. The -20 to +85 °C figure is the chip ambient range, not the measurement range — the thermocouple itself goes to 1024 °C while the chip must stay within its own limits, a distinction that matters in hot enclosures. Choose MAX6675 for simple high-temperature thermocouple jobs and MAX31865 for precision RTD jobs; the two solve different sensor problems and do not substitute. The ISA code is SOIC-8, T denotes tape and reel. Evidence: ADI/Maxim datasheet and distributor listings confirm K-type, 12-bit, 0.25 °C resolution, 0-1024 °C range and SOIC-8.
