Temperature-Sensor IC Monitors Seven Channels Simultaneously

A small-footprint (8.5 by 6 mm), seven-channel temperature-sensor IC reads thermal diodes or thermistors to 1°C accuracy. The MAX6697 measures its own temperature as well as the temperature of up to six external locations, such as CPUs, GPUs, or memory devices. For industrial applications, the MAX6698 can measure three thermistors and three remote diodes. Both chips communicate through an SMBus interface and operate from a 3- to 5-V supply. Operating current is 500 µA, while standby is 3 µA. Prices start at $3.75 each in lots of 2500 and up.
