Analog Devices Inc. MAX30210 I2C Digital Temperature Sensor
Analog Devices MAX30210 I2C Digital Temperature Sensor operates from 1.7V to 2.0V supply voltage and is a high-accuracy, low-power digital temperature sensor. It has ±0.1°C accuracy from +20°C to +50°C and ±0.15°C accuracy from -20°C to +85°C. The MAX30210 also has a 16-bit resolution (0.005°C).
The device uses a standard I2C serial interface to communicate with a host controller. There are four functional I/Os. Those functions include a dedicated interrupt pin, a power-down functional pin, a shared external convert, and two target address select pins. The Analog Devices MAX30210 consists of a 64-word FIFO for the temperature data, FIFO full alert, and high and low-threshold digital temperature alarms. The device is available in a 0.968mm x 0.968mm x 0.5mm, 9-pin WLP package.
