MAX31889ALT+

MAX31889ALT+ is a temperature sensor. This 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 conversion, 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. It is used in applications such as precision temperature monitoring, RTD replacement, internet of things (IoT) sensors.

• Operating voltage range from 1.7V to 3.6V
• Operating current is 68µA typical at (during conversion, VDD = 1.7V to 3.6V, TA = +25°C)
• Standby current is 0.55µA typical at (VDD = 3.6V, TA = +25°C)
• Conversion time is 16.5ms typical at (VDD = 1.8V, TA = +25°C)
• High and low temperature alarms, configurable interrupt output pin
• 32-word FIFO for temperature data, configurable convert temperature input pin
• Input capacitance is 10pF typical at (VDD = 1.8V, TA = +25°C)
• Serial clock frequency is 400KHz maximum at (VDD = 1.8V, TA = +25°C)
• Operating temperature range from -40°C to +125°C
• 6-pin μDFN package
