Product Overview
The TC77 is a serially accessible digital temperature sensor designed for low-cost, small-form-factor applications. It outputs temperature as a 13-bit digital word via a SPI and MICROWIRE compatible interface. Key advantages include high accuracy over a wide temperature range, low power consumption in both continuous conversion and shutdown modes, and ease of use, making it an ideal solution for thermal management in various systems.
