Datenblatt MAXIM MAX31865

Description

• Support 100 Ohm to 1kOhm (0"C) platinum resistance RTD (PT100 to PT1000)
• SPI compatible interface
• 15bit ADC resolution with a nominal temperature resolution of 0.03125 "C(variable with RTD nonlinearity)
• The total accuracy is maintained at 0.5 o C (0.05% of full scale) under the entireworking conditions
• fully differential VREF input
• Conversion time: 21ms (maximum)
• Integrated fault detection to increase system stability: (RTD open circuit, RTD shortcircuit to voltage outside the range or short circuit of RTD components)
