Frequently Asked Questions
What ADC resolution and temperature measurement range does the MAX31865AAP+T support with PT100 or PT1000 sensors?
The MAX31865AAP+T provides 15-bit ADC resolution for RTD measurements spanning -200°C to +850°C when connected to PT100 or PT1000 sensors. This resolution translates to temperature step sizes of approximately 0.03°C per LSB at 0°C, enabling the precision temperature monitoring required in industrial process control, pharmaceutical production, and laboratory calibration equipment.
Which RTD wiring configurations does the MAX31865AAP+T support to minimize lead resistance errors?
The MAX31865AAP+T supports 2-wire, 3-wire, and 4-wire RTD connection configurations. The 4-wire Kelvin connection eliminates lead resistance errors entirely, providing the highest measurement accuracy for long cable runs or low-resistance PT100 sensors. The 3-wire configuration offers a practical compromise for industrial installations, while the 2-wire mode is suitable for short lead lengths with minimal resistance below 1 Ω.
How does the MAX31865AAP+T simplify integration into a microcontroller-based temperature logger compared to a discrete RTD signal conditioning circuit?
The MAX31865AAP+T integrates all RTD signal conditioning — including excitation current source, 15-bit ADC, and fault detection — into a single 20-pin SSOP IC that communicates over a 3-wire SPI interface at supply voltages of 3.3 V. A discrete solution would require an external precision current source, amplifier, and 16-bit ADC, consuming 3 to 5 times more board area and requiring significantly more calibration. The MAX31865 also includes automated fault detection for open-circuit, short-circuit, and out-of-range RTD resistance conditions.
