Texas Instruments (TI) has introduced a new temperature sensor family that offers ±0.1°C accuracy across a wide temperature range and helps simplify system design for industrial and medical applications. The TMP117 is the first single-chip temperature sensor to offer similar performance to platinum resistance temperature detectors (RTDs) while significantly reducing design complexity and power consumption, and the TMP117M, a digital temperature sensor for medical applications, supports requirements for medical thermometers. The new devices enable engineers to more quickly develop highly accurate, ultra-low-power patient monitoring, field transmitter and metering applications.
Delivering ±0.1°C accuracy across a wide range, with zero calibration during manufacturing, the new sensor family saves designers time and reduces production costs for systems requiring high accuracy.
- Supports clinical temperature requirements: For medical applications, the TMP117M provides ± 0.1°C accuracy from 30°C to 45°C and supports American Society for Testing and Materials (ASTM) E1112 and International Organization for Standardization (ISO) 80601 requirements for patient thermometers.
- Achieve Class-AA RTD accuracy for industrial applications: The TMP117 provides a direct readout of temperature, with no additional linearization or acquisition error, and maintains accurate temperature over a wide range:
- ±0.1°C from -20°C to +50°C.
- ±0.15°C from -40°C to +50°C.
- ±0.2°C from -40°C to +100°C.
- ±0.25°C from -55°C to +125°C.
- ±0.3°C from -55°C to +150°C.
