ADT7484A Datasheet, PDF (1/14 Pages) Analog Devices – Digital Temperature Sensor with SST Interface

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.
Features
• 1 On-Chip Temperature Sensor
• 1 or 2 Remote Temperature Sensors
• Simple Serial Transportt (SSTt) Interface Rev 1 Compliant
• These are Pb−Free Devices
Applications
• Personal Computers
• Portable Personal Devices
• Industrial Sensor Nets
