Product Overview
The AT30TS74 is a complete, precise digital temperature sensor designed for monitoring local temperatures in various applications. It integrates a high-precision sensor, programmable temperature alarms, and a 2-Wire I2C/SMBus serial interface. The device offers a wide temperature measurement range (-55C to +125C) with high accuracy, user-configurable resolution, and flexible alarm settings. Its low-power dissipation and shutdown mode make it ideal for power-sensitive applications. The AT30TS74 is factory-calibrated, requires no external components, and is pin and software compatible with industry-standard LM75-type devices.
