3 Description

The TMP119 is a high-precision digital temperature

sensor. The device is designed to help meet

ASTM E1112 and ISO 80601 accuracy requirements

for electronic patient thermometers. The TMP119

provides a 16-bit temperature result with a resolution

of 0.0078°C and an accuracy of up to ±0.08°C

across the temperature range of 0°C to 45°C with

no calibration. The TMP119 has an 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

TMP119 operates from 1.7V to 5.5V and typically

consumes 3.5μA for a 1Hz conversion cycle.

For non-medical applications, the TMP119 can serve

as a single chip digital alternative to a Platinum

RTD. The TMP119 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 TMP119 simplifies the design effort by

removing many of the complexities of RTDs such

as precision references, matched traces, complicated

algorithms, and calibration. The device is designed

to be strain tolerant, allowing robustness over typical

strains often seen in PCB manufacturing, including

device soldering, molding, underfill, and board flexing.

The TMP119 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.
