Product Overview
The TMP117 is a Texas Instruments digital temperature sensor for systems that require digital temperature measurement over a broad free-air operating range. The recommended operating free-air temperature range is -55 °C to 150 °C, with specified temperature accuracy limits across several ranges, including ±0.1 °C maximum from -20 °C to 50 °C and ±0.3 °C maximum from -55 °C to 150 °C.
Temperature output is provided as a 16-bit result with 0.0078 °C/LSB resolution. The device communicates through an SMBus and I2C-compatible digital serial interface, and the ADD0 address-select function supports up to four devices on a single bus. Integrated 48-bit general-purpose EEPROM is available for system use.
The TMP117 is available in WSON (6) 2.00 mm × 2.00 mm and DSBGA (6) 1.53 mm × 1.00 mm packages. Supply operation is specified from 1.8 V to 5.5 V across -55 °C to 150 °C, with a 1.7 V minimum allowed across -55 °C to 70 °C. Low-current operation is supported by 3.5 µA consumption at a 1-Hz conversion cycle and 150 nA shutdown current.

Procurement Notes
When requesting a quote for TMP117, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For memory and storage sourcing, density, organization, speed grade, voltage, package, temperature grade, date code, lifecycle status and original packing condition should be verified before approval.
FAQ
