ADT7486A

ADT7484A/ADT7486A Digital Temperature Sensor with SST Interface The ADT7484A/ADT7486A are simple digital temperature sensors for use in PC applications with a Simple Serial Transport (SST) interface. These devices can monitor their own temperature as well as the temperature of one (ADT7484A) or two (ADT7486A) remote sensor diodes. The ADT7484A/ADT7486A are controlled by a single SST bidirectional data line. The devices are fixed-address SST clients where the target address is chosen by the state of the two address pins, ADD0 and ADD1.
