Analog Devices Inc. (ADI, Wilmington, MA) announced its new ADT7461 enhanced digital temperature sensor with capabilities important for next-generation processors. The new temp sensor can monitor a wide temperature range, and automatically cancels temperature errors due to resistance in series with the remote sensor. The ADT7461 is well suited for a range of applications, including desktop and notebook computers, industrial controls, automotive, instrumentation, and embedded systems.
The default temperature measurement range of 0°C to 127°C can be configured to a remote-sensor extended range of -64°C to +191°C, used in practice to measure temperatures from -40°C to 150°C. The device automatically compensates for as much as 1,000 ohms of series parasitic resistance between the sensor and recording circuits, in most cases eliminating the need for system calibration.
The ADT7461 temperature sensor is sampling in eight-pin small-outline integrated circuit and eight-pin microSOIC packages and is priced at $1.70 per unit in 1,000-piece quantities.
