Accurate Temperature Sensor for Precision Measurement Applications
Texas Instruments has announced a low-power, +/-0.5C accurate, digital-output temperature sensor. The TMP275 is well-suited for precision temperature measurement in a wide range of communications, computer, consumer, environmental, industrial and instrumentation applications.
The high accuracy of the TMP275 enables more efficient thermal and power management, while low power consumption extends battery life and minimizes self-heating. The TMP275 can be configured for a wide variety of systems including battery-powered devices, HVAC equipment, notebook computers, cell phones and base stations.
The TMP275 features +/-0.5C (max) accuracy from +10C to +85C and +/-0.75C (max) accuracy from 0C to +100C. The two-wire serial interface is I2C/SMBus-compatible. Additional features include 50uA power consumption, programmable resolution (9- to 12-bit), 0.1uA shutdown current mode, excellent stability over temperature and a wide temperature range of -40C to 125C. The device allows up to eight
different addresses for flexibility in interface bus designs.
