Product Overview
TMP119AIYBGR is TI’s ultra-high-accuracy digital temperature sensor in a very small DSBGA package. It specifies ±0.08°C maximum error from 0°C to 45°C and maintains tight limits over much wider ranges, while retaining 16-bit 0.0078°C digital resolution.
The exact device also emphasizes strain tolerance. Mechanical stress from soldering, underfill, molding or board flex can shift precision temperature sensors; TMP119 is designed to reduce that source of error, which is particularly relevant to tiny WCSP-style assemblies.
Its small thermal mass can give fast local response, but the same small package makes PCB thermal gradients and assembly mechanics more important. Accuracy at the IC is only useful if the IC temperature represents the target being measured.

Functional Highlights
Strain tolerance is a system-accuracy feature
For sub-0.1°C measurement goals, package stress can become comparable to the electrical sensor error. TMP119 specifically targets this mechanism, making board assembly and mechanical environment part of device selection.
The tightest accuracy window is 0°C to 45°C
The device remains accurate outside that range, but the specified maximum error steps to larger limits across progressively wider temperature spans.
Design Considerations
- Model mechanical strain and thermal gradients when using the DSBGA in a precision measurement point.
- Use the exact accuracy band that covers the product’s operating temperature.
- Avoid underfill, copper geometry or nearby dissipation choices that make the sensor temperature differ from the target.
