MAX30205
MAX30205
Human Body Temperature Sensor
General Description
The MAX30205 temperature sensor accurately measures
temperature and provide an overtemperature alarm/
interrupt/shutdown output. This device converts the
temperature measurements to digital form using a high-
resolution, sigma-delta, analog-to-digital converter (ADC).
Accuracy meets clinical thermometry specification of
the ASTM E1112 when soldered on the final PCB.
Communication is through an I2C-compatible, 2-wire
serial interface.
The I2C serial interface accepts standard write byte, read
byte, send byte, and receive byte commands to read the
temperature data and configure the behavior of the open-
drain overtemperature shutdown output.
The MAX30205 features three address select lines with a
total of 32 available addresses. The sensor has a 2.7V to
3.3V supply voltage range, low 600µA supply current, and
a lockup-protected I2C-compatible interface that make it
ideal for wearable fitness and medical applications.
This device is available in an 8-pin TDFN package and
operates over the 0NC to +50NC temperature range.
