TI Targets Thermal Measurements with 0.5C Accurate, Digital Sensor

7/2/2003 - Texas Instruments (TI) Incorporated (NYSE: TXN) introduced a digital-output temperature sensor integrated circuit (IC) from the company´s Burr-Brown product line which features an SPI-compatible interface and tiny SOT23 packaging. The device is ideal for thermal measurements in a variety of communications, computer, consumer, industrial and instrumentation applications.

The TMP122 is capable of measuring temperatures within 0.5 degrees Celsius accuracy (1.5C max) over a temperature range of -25C to +85C, with operation from -55C to +150C. Low supply current (50uA), a shutdown feature (0.1uA) and a supply range from 2.7V to 5.5V make the device well suited for low-power applications. The TMP122 provides programmable resolution (9 to 12 bits) and programmable setpoints for the alert pin.

"The TMP122 is the latest addition to TI's growing portfolio of temperature sensors which offers a superior combination of accuracy, resolution, versatility and low power. Due to its programmable features, small packaging and wide temperature range, the TMP122 will find its place in a very diverse set of applications," said Tadija Janjic, strategic marketing engineer for TI's high-performance linear products.

The TMP122 is optimized for space-sensitive, low-power systems such as computer peripheral thermal protection, notebook computers, cell phones, thermostat controls, battery management and environmental monitoring.

Available Today
The TMP122 is packaged in a SOT23-6, and is available now from TI and its authorized distributors. Suggested resale price is $0.99 in 1,000 piece quantities.
