Maxim (MAX31855KASA+) Temperature Sensor IC, ± 2°C, -200°C, 1350°C, 8 Pins

Temperature Sensor IC, Thermocouple, Digital, ± 2°C, -200 °C, 1350 °C, NSOIC, 8PinsProduct OverviewThe MAX31855KASA+ is a cold junction compensated thermocouple to digitalconverter with built-in 14bit analogue to digital converter in 8 pin NSOICpackage. The device contains cold junction compensation sensing and correction,digital controller, SPI compatible interface and associated control logic. It isdesigned to work in conjunction with an external microcontroller (µC) inthermostatic, process control or monitoring applications. The MAX31855K performscold junction compensation and digitizes the signal from K type thermocouplewith measuring temperature range of -200°C to +1350°C. The Thermocoupletemperature gain and offset error ((41.276µV/°C nominal sensitivity)) is ±2°C atT (thermocouple) = -200°C to +700°C, TA = -20°C to +85°C. The data outputs in asigned 14bit, SPI compatible read only format.Supply voltage range from 3V to 3.6VSerial clock frequency of 5MHzIntegration reduces design time and lowers system costDetects thermocouple shorts to GND or VCC and open thermocouple14bit, 0.25°C resolution converterPower supply current is 900µAThermocouple input bias current is 100nATemperature conversion time is 70ms and thermocouple conversion power-up time is200msApplicationsSensing & Instrumentation, Industrial, HVAC, AutomotiveProduct InformationIC Output Type: DigitalSensing Accuracy Range: ± 2°CSensing Temperature Min: -200°CSensing Temperature Max: 1350°CSensor Case Style: NSOICNo. of Pins: 8PinsSupply Voltage Min: 3VSupply Voltage Max: 3.6VProduct Range: -MSL: MSL 1 - Unlimited
