Digital temp sensor improves system reliability

Digital temp sensor improves system reliability

The AT30TS750 family of high-precision digital temperature sensors integrates both nonvolatile registers and serial EEPROM memory. This combination allows for user-configured settings to be retained across power cycles to simplify the system design, reduce processor start-up code, improve reliability, and ensure proper operation.

The sensor integrates 2, 4, and 8 Kbits of serial EEPROM to store system parameters and user preference data. The user can then access the EEPROM, which is fully functional and drop-in compatible with industry-standard I2 C serial EEPROMs. It converts temperatures from –40° to 125°C to a digital word and provides a typical accuracy of ±0.5°C over the operating temperature range of 0° to 85°C. It also includes programmable high- and low-temperature alarms and a user-selectable temperature resolution up to 12 bits. ($0.48 for 5,000 — available now.)
