Highly accurate, 8-channel temperature sensor reduces board area
Maxim introduced the MAX6581, a ±1 degree Celsius accurate, 8-channel temperature sensor. It has seven remote sensing channels to monitor ASICs, FPGAs, CPUs, and boards with multiple hot spots. Each remote channel includes series resistance cancellation and beta compensation for best accuracy. Because the MAX6581 contains eight channels of temperature sensing, but requires only a single I2C address for these eight channels, it reduces board area and overall system cost.
ThisOffered in a 4mm x 4mm, 24-pin TQFN package with an exposed pad, the MAX6581 is specified for an operating temperature range of -40 degrees Celsius to +125 degrees Celsius. Prices start at $1.24 (1000-up, FOB USA).
