Maxim Integrated MAX30208 I2C Digital Temperature Sensor

Featuring low-power, high-accuracy characteristics

Operating from a 1.7V to 3.6V supply voltage, the Maxim Integrated MAX30208 is a low-power, high-accuracy digital temperature sensor with nearly on-point accuracy.

The MAX30208 sensor features ±0.1°C accuracy from +30°C to +50°C, and ±0.15°C accuracy from 0°C to +70°C. With a 16-bit resolution (0.005°C), the MAX30208 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 Maxim Integrated MAX30208 includes a 32-word FIFO for the temperature data and also includes high and low threshold digital temperature alarms. The MAX30208 is available in a 2mm x 2mm x 0.75mm, 10-pin Thin LGA package.

Evaluation System

MAX30208EVSYS

The MAX30208EVSYS evaluation system (EV system) provides a single platform to evaluate the MAX30208, consisting of two boards connected through headers, a MAX32630FTHR microcontroller board, and the MAX30208 interface board.

The evaluation system also includes a flex PCB that holds the MAX30208 IC. The MAX32630FTHR contains the firmware necessary to use the PC GUI program and also provides power to the MAX30208 interface board. The MAX30208 interface board ships with jumpers pre installed to allow quick evaluation of the MAX30208.
