3 Description
The TMP117 is a high-precision digital temperature
sensor. It is designed to meet ASTM E1112 and ISO
80601 requirements for electronic patient
thermometers. The TMP117 provides a 16-bit
temperature result with a resolution of 0.0078°C and
an accuracy of up to ±0.1°C across the temperature
range of -20°C to 50°C with no calibration. The
TMP117 has in interface that is I2C- and SMBus™-
compatible, programmable alert functionality, and the
device can support up to four devices on a single
bus. Integrated EEPROM is included for device
programming with an additional 48-bits memory
available for general use.
The low power consumption of the TMP117
minimizes the impact of self-heating on measurement
accuracy. The TMP117 operates from 1.8 V to 5.5 V
and typically consumes 3.5 μA.
For non-medical applications, the TMP117 can serve
as a single chip digital alternative to a Platinum RTD.
The TMP117 has an accuracy comparable to a Class
AA RTD, while only using a fraction of the power of
the power typically needed for a PT100 RTD. The
TMP117 simplifies the design effort by removing
many of the complexities of RTDs such as precision
references, matched traces, complicated algorithms,
and calibration.
The TMP117 units are 100% tested on a production
setup that is NIST traceable and verified with
equipment that is calibrated to ISO/IEC 17025
accredited standards.TMP117AIDRVR
