Maxim Integrated Products Inc. (Sunnyvale, CA) announced its new MAX6662 digital temperature sensor, which provides a measurement accuracy to within ±1 degree C from 20 to 45 degrees C, ±3 degrees C from -40 to 125 degrees C, and ±5 degrees C from 125 to 150 degrees C. It has an internal 12-bit ADC that provides 0.0625 degrees C resolution. The MAX6662 operates via a 3V to 5.5V, 300µA (typical) supply. It consumes just 1µA.
The device performs temperature conversion every 0.5 seconds. Temperature data from the most recent completed conversion is available over the SPI-compatible bus interface and can be read at any time. The SPI-compatible interface operates at speeds up to 10MHz. When a temperature measurement falls outside the user-programmed limits, it generates an interrupt output on the open-drain alert pin. The overt comparator output, also equipped with programmable thresholds, can be used to shut down the system when the temperature exceeds safe operating levels.
Pricing starts at $1.37 in quantities of 1,000.
