Datasheet Maxim MAX31889

EVALUATION KIT AVAILABLE Click here for production status of specific part numbers. MAX31889 ±0.25°C Accurate I2C Temperature Sensor General Description Benefits and Features The MAX31889 operates from a 1.7V to 3.6V supply voltage, and is a low-power, high-accuracy digital temperature
sensor with ±0.25ºC accuracy from -20ºC to +105ºC and
± 0.65ºC accuracy from -40ºC to +125ºC. The MAX31889
has 16-bit resolution (0.005ºC). ● High Accuracy and Precision
• ±0.25ºC Accuracy from -20ºC to +105ºC
• ±0.65ºC Accuracy from -40ºC to +125ºC 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. Applications
