±0.1°C Accurate, I²C Digital Temperature Sensor

Description

Create a design and simulate using EE-Sim^® tools:

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.
