Dallas Semi Intros DS620 Digital Temperature-Sensor IC

Dallas Semiconductor Corp. (Dallas, TX) introduced its new DS620 digital temperature-sensor IC, which is suitable for low-power and battery-operated systems, and operates from a low supply-voltage range of 1.7 V to 3.5 V. The ICs are factory-calibrated to an accuracy of ±0.5 °C (maximum) over its entire supply-voltage range, and up to 70 °C, and is ±2 °C (maximum) accurate over the -55 °C to +125 °C operating temperature range.

The DS620 can be configured to measure temperature at power-up, thus enabling its thermostat functionality to operate in a stand-alone mode without user or processor intervention. When not in use, the thermostat output can act as a general-purpose programmable output.

The devices are is available in eight-pin microSOP packages, and are priced at $1.66 for 1,000-unit orders (minimum).
