Sunnyvale, Calif. Small size, high precision, and user flexibility make the MAX6697/MAX6698 precision 7-channel temperature sensors from Maxim Integrated Products Inc. a suitable choice for notebook, desktop, and industrial applications, where accurate temperature readings of multiple locations are a must.
With 1 °C accuracy, the MAX6697 measures its own temperature and the temperature of up to six external locations such as CPUs, GPUs, memory devices, and other locations important in notebook and desktop applications. The MAX6698 offers temperature measurements of three thermistors and three remote diodes for industrial applications. These devices offer built-in flexibility. The user can program the temperature threshold of alarm outputs, which can serve as an interrupt or be connected to a system fan or other thermal-management circuitry.
The MAX6697/MAX6698 communicate through the Systems Management Bus (SMBus) interface. They operate from a 3-V to 5-V supply-voltage range and consume only 500 μA of supply current and only 3 μA in standby mode. The MAX6697/MAX6698 are specified over a wide -40 °C to +125 °C temperature range.
Housed in a small 8.5mm x 6mm, 20-pin QSOP package, prices start at $3.75 each (2500-up, FOB USA).
