Description
The AT30TS74-SS8M-T is a complete, precise temperature monitoring device designed for use in a variety of applications which require the measuring of local temperatures as an integral part of the system's function and/or reliability. The AT30TS74-SS8M-T device combines a high-precision digital temperature sensor, programmable high and low temperature alarms, and a 2-Wire I2 C and SMBus (System Management Bus) compatible serial interface into a single compact package.
The temperature sensor can measure temperatures over the full -55C to +125C temperature range and has a maximum accuracy of ±2.0C from -20C to +100C. The result of the digitized temperature measurements are stored in one of the AT30TS74-SS8M-T internal registers, which is readable at any time through the device's serial interface.
The AT30TS74-SS8M-T utilizes flexible, user-programmable internal registers to configure the temperature sensor's performance and response to high and low temperature conditions. A dedicated alarm output activates if the temperature measurement exceeds the user-defined temperature and fault count limits. To reduce current consumption and save power, the AT30TS74-SS8M-T features a Shutdown mode which turns off all internal circuitry except for the internal Power-On Reset (POR) and serial interface circuits. The AT30TS74-SS8M-T is factory-calibrated and requires no external components to measure temperature. With its flexibility and high-degree of accuracy, the AT30TS74-SS8M-T is ideal for extended temperature measurements in a wide variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.
