Highly accurate digital temperature sensors for RTD-based and medical designs

Texas Instruments has a new temperature sensor family that offers ±0.1C accuracy across a broad temperature range and helps simplify system design for industrial and medical applications. The TMP117 is claimed to be the first single-chip temperature sensor to provide similar performance to platinum RTDs while significantly lessening design complexity and power consumption, and the TMP117M, a digital temperature sensor for medical applications, supports demands for medical thermometers. The new devices allow engineers to more quickly develop highly accurate, ultra-low-power patient monitoring, field transmitter and metering applications. Delivering ±0.1C accuracy across a broad range, with zero calibration during manufacturing, the new sensor family saves designers time and lessens production costs for systems needing high accuracy.
