Product Overview
The TC72 is a digital temperature sensor designed for precise temperature monitoring across a wide range, from -55C to +125C. It features a 10-bit resolution, providing 0.25C per bit, and offers high accuracy with a maximum deviation of 2C from -40C to +85C and 3C from -55C to +125C. The sensor communicates via an SPI-compatible interface, eliminating the need for external components. It supports both continuous temperature conversion for real-time monitoring and a power-saving one-shot measurement mode. Available in compact 8-pin MSOP and 3x3 mm DFN packages, the TC72 is ideal for thermal management in personal computers, servers, storage devices, entertainment systems, office equipment, datacom equipment, and mobile phones.
