MyMaxim SubscriptionsProduct Details
The MAX30208 operates from a 1.7V to 3.6V supply voltage, and is a low-power, high-accuracy digital temperature sensor with ±0.1°C accuracy from +30°C to +50°C and ±0.15°C accuracy from 0°C to +70° C. The MAX30208 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 conversion, while GPIO0 can be configured to generate an interrupt for selectable status bits.
The MAX30208 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 0.75mm, 10-pin Thin LGA package.

How to Accurately Measure Human Body Temperature Using the MAX30208Description
The MAX30208 evaluation system (EV system) provides a single platform to evaluate the MAX30208, a temperature sensor with ±0.1°C accuracy. The EV system consists of two boards connected through headers, a MAX32630FTHR microcontroller board, and the MAX30208 interface board. Also included with the EV system is 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 preinstalled to allow quick evaluation of the MAX30208.
