MAX30208 ±0.1°C Accurate, I2C Digital Temperature Sensor General Description Benefits and Features
The MAX30208 operates from a 1.7V to 3.6V supply ● High Accuracy and Precision voltage, and is a low-power, high-accuracy digital tem- • ±0.1°C Accuracy from +30°C to +50°C perature sensor with ±0.1°C accuracy from +30°C to • ±0.15°C Accuracy from +0°C to +70°C +50°C and ±0.15°C accuracy from 0°C to +70°C. The ● Low Power Consumption MAX30208 has 16-bit resolution (0.005°C). • 1.7V to 3.6V Operating Voltage The device uses a standard I2C serial interface to com- • 67μA Operating Current During Measurement municate with a host controller. Two GPIO pins are avail- • 0.5μA Standby Current able. GPIO1 can be configured to trigger a temperature • 15ms Integration Time conversion, while GPIO0 can be configured to generate ● Small Size an interrupt for selectable status bits. • 2mm x 2mm x 0.75mm, 10-Pin Thin LGA The MAX30208 includes a 32-word FIFO for the tempera- ● Safety and Compliance ture data and also includes high and low threshold digital • High and Low Temperature Alarms temperature alarms. The device is available in a 2mm x 2mm x 0.75mm, 10-pin Thin LGA package. ● Digital Interface • Configurable Convert Temperature Input Pin
Applications
• Configurable Interrupt Output Pin • 32-Word FIFO for Temperature Data ● Wearable Body Temperature Monitors • 4 I2C Addresses Available—More Addresses ● Medical Thermometers Available by Request ● Internet of Things (IoT) Sensors • Unique ROM IDs Allow Device to be NIST Traceable
