Description
General part information
MAX31888 Series
The MAX31888 is a 1-Wire high precision, low power digital temperature sensor with ±0.25ºC accuracy from -20ºC to +105ºC for precision temperature monitoring. The MAX31888 operates at 68μA operating current during measurement and has 16-bit resolution (0.005ºC).The sensor communicates with a microcontroller over a 1-Wire®bus that requires only one data line (and a ground reference) for communication. In addition, the sensor can derive power directly from the data line through "parasite power", eliminating the need for an external power supply. Each MAX31888 has its own unique 64-bit registration number that is factory programmed into the chip. This unique 64-bit registration number acts as the node address in the case of a multi-drop 1-Wire®network. In multi-drop networks, optional GPIO pins can be used as address bits to identify each device's physical location.The MAX31888 is available in a 6-pin µDFN package. The power supply voltage range is from 1.7V to 3.6V for external power supplies. The operating temperature range is from -40°C to +125°C.ApplicationsPrecision Temperature MonitoringRTD ReplacementInternet of Things (IoT) SensorsCold Chain
