MAX31865AAP+ Description

Short technical summary and product information.

The MAX31865AAP+ is a resistance-to-digital converter from Analog Devices, optimized for platinum resistance temperature detectors (RTDs). It simplifies the conversion of RTD resistance to a digital value, supporting 2-, 3-, and 4-wire sensor connections for platinum RTDs ranging from 100Ω to 1kΩ at 0°C (PT100 to PT1000).

 

This IC features a 15-bit delta-sigma ADC, providing a nominal temperature resolution of 0.03125°C and a total accuracy of ±0.5°C over all operating conditions. It operates with a voltage range of 3V to 3.6V and communicates via an SPI-compatible interface. The MAX31865AAP+ includes integrated fault detection for RTD and cable open/short conditions, along with ±45V input protection, enhancing system reliability.

 

Designed for applications in industrial equipment, medical equipment, and instrumentation, the MAX31865AAP+ comes in a 20-SSOP package suitable for surface mounting. Its integration lowers system cost and simplifies design efforts, reducing design cycle time. The maximum conversion time is 21ms.
