Product Overview
TMP117AIDRVR is a precision digital temperature sensor with a specified ±0.1°C maximum error from −20°C to 50°C and calibrated operation extending to 150°C. It is designed for applications where the temperature-sensor error itself must be small enough to compete with a precision platinum RTD implementation.
The device combines 16-bit conversion, selectable averaging, programmable alert, a digital offset register and 48 bits of general-purpose EEPROM. The offset feature is useful when a finished assembly has a known thermal-system bias that should be corrected without changing the raw sensor hardware.
Compared with TMP116, TMP117 gives tighter accuracy and higher maximum operating temperature; compared with TMP119, it trades the newer strain-tolerant WCSP implementation for a larger 2 mm WSON package.

Functional Highlights
The ±0.1°C specification has a defined temperature range
The tighter limit applies from −20°C to 50°C. Wider temperature spans have progressively larger maximum error, so medical or calibration-grade specifications should use the exact applicable band.
Digital offset supports system-level correction
A board may have repeatable temperature difference between the IC junction and the target object. The offset register can correct a characterized bias, but it cannot remove a changing thermal gradient caused by poor placement.
Design Considerations
- Use the appropriate supply minimum for the required maximum operating temperature.
- Characterize package-to-target thermal gradients before relying on digital offset.
- Keep self-heating and nearby power dissipation below the total sensor error budget.
