MAX30210
±0.1°C Accurate, Ultra-Small, Low-Power I C
Digital Temperature Sensor
General Description
Benefits and Features
The MAX30210 operates from 1.7V to 2.0V supply volt-
age, and is a low-power, high-accuracy digital temperature
sensor with ±0.1°C accuracy from +20°C to +50°C and
±0.15°C accuracy from -20°C to +85°C. The MAX30210
has a 16-bit resolution (0.005°C).

The device uses a standard I C serial interface to com-
municate with a host controller. There are four functional
I/Os. Those functions include a dedicated interrupt pin, a
shared external convert and power-down functional pin,
and two target address select pins.
● Safety and Compliance
The MAX30210 includes a 64-word FIFO for the tempera-
ture data and also includes high and low threshold digital
temperature alarms along with FIFO full alert. The device
is available in a 0.968mm x 0.968mm x 0.5mm, 9-pin WLP
package.
