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 I
2
C-compatible, 2-wire
serial interface.
The I
2
C 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 I
2
C-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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

Note 3:
Limits are 100% production tested at T
A
= +25NC. Limits over the operating temperature range and relevant supply voltage
range are guaranteed by design and characterization. Typical values are not guaranteed.
Note 4:
All voltages are referenced to ground. Currents entering the IC are specified positive.
Note 5:
These limits represent a 6-sigma distribution of shipped devices and a 3-sigma distribution when these devices are sol-
dered down on the PCB. Sample period > 10s to eliminate self-heating effects.
Note 6:
All timing specifications are guaranteed by design.
Note 7:
Holding the SDA line low for a time greater than t
TIMEOUT
causes the devices to reset SDA to the idle state of the serial
bus communication (SDA released).
Note 8:
A master device must provide a hold time of at least 300ns for the SDA signal to bridge the undefined region of SCL’s fall-
ing edge.
Note 9:

= total capacitance of one bus line in pF. Tested with C
