Overview
The TMP114AIYMTR, produced by Texas Instruments, is a high-accuracy, I2C-compatible digital temperature sensor. It is packaged in an ultra-thin 4-pin PicoStar (DSBGA) package with a height of just 0.15 mm, making it ideal for volume-constrained systems. The sensor is factory calibrated on a NIST traceable setup and features a 16-bit analog-to-digital converter (ADC) that provides a temperature resolution of 0.0078°C. It operates from a supply voltage range of 1.08 V to 1.98 V and has a low average supply current of less than 0.7 μA, maximizing battery life in portable applications.
