Maxim's temperature sensor measures with 1°C accuracy

The new precision five-channel temperature sensor from Maxim Integrated Products accurately measures its own temperature and the temperature of up to four external locations with 1°C temperature accuracy. The four remote locations can be CPUs, GPUs, memory devices and other locations important in notebook applications.

Housed in a small 16-pin QSOP or TSSOP package, the MAX6699 sensor also allows the user to program the temperature threshold of alarm outputs. Designed for user flexibility, these outputs can serve as an interrupt, or can be connected to a system fan or other thermal management circuitry.

Maxim added that the combination of high precision, small size and high flexibility makes the MAX6699 the ideal choice for notebook applications, where accurate temperature readings of multiple locations are a must. This new product communicates through an SMBus interface, operates from a 3V to 5V supply voltage range, and consumes 500?A of supply-current which drops to 3?A in standby mode.

The MAX6699 is specified over the -40°C to 125°C temperature range. Prices start at $2.75 (2,500-up, FOB USA).
