Description
General part information
MAX31889 Series
The MAX31889 operates from a 1.7V to 3.6V supply voltage, and is a low-power, high-accuracy digital temperature sensor with ±0.25°C accuracy from -20°C to +105°C and ± 0.65°C accuracy from -40°C to +125°C. The MAX31889 has 16-bit resolution (0.005°C).The device uses a standard I2C serial interface to communicate with a host controller. Two GPIO pins are available. GPIO1 can be configured to trigger a temperature converison, while GPIO0 can be configured to generate an interrupt for selectable status bits.The MAX31889 includes a 32-word FIFO for the temperature data and also includes high and low threshold digital temperature alarms. The device is available in a 2mm x 2mm x 0.8mm, 6-pin, µDFN package.ApplicationsInternet of Things (IoT) SensorsPrecision Temperature MonitoringRTD Replacement
