com Digital Temperature Sensor with SST Interface ADT7484A/ADT7486A FEATURES 1 on-chip temperature sensor 1 or 2 remote temperature sensors Simple Serial Transport™ (SST™) interface Rev 1 compliant GENERAL DESCRIPTION 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 fixedaddress SST clients where the target address is chosen by the state of the two address pins, ADD0 and ADD1.
