TMP118

The TMP118 is a high-accuracy digital temperature sensor manufactured by Texas Instruments, designed for precise temperature measurement in industrial, consumer, and automotive applications. It features a ±0.1°C accuracy over the full operating range of −40°C to +125°C, making it ideal for systems requiring reliable thermal monitoring. The device uses an integrated 16-bit sigma-delta ADC to provide high-resolution measurements with low noise, ensuring stable and repeatable results even in harsh environments. This sensor supports both I²C and SMBus communication protocols, enabling seamless integration into existing system architectures. Its flexible configuration allows users to set up alert thresholds, choose between continuous or periodic conversion modes, and configure resolution settings from 9 to 16 bits. Additionally, the TMP118 includes a programmable temperature window comparator that can generate an interrupt signal when the measured temperature exceeds user-defined limits, reducing microcontroller load and improving system efficiency. The TMP118 operates on a supply voltage range of 1.7V to 3.6V, making it suitable for low-power applications such as battery-powered devices. It also offers a low quiescent current of just 1.5 µA in shutdown mode, enhancing energy efficiency. With a compact 3mm × 3mm WSON package, it provides space-saving design flexibility for densely populated PCBs. Key features include built-in self-test functionality for diagnostic purposes, a factory-calibrated internal reference for consistent performance, and support for multiple address pins to allow up to four devices on the same bus. These capabilities make the TMP118 well-suited for applications like thermal management in power supplies, HVAC systems, battery packs, and medical equipment where precision, reliability, and low power are critical. Its robust design ensures long-term stability and minimal drift over time, further reducing maintenance needs in field-deployed systems.
