ADT7485A

Temperature Sensor and

Voltage Monitor with

Simple Serial Transport

The ADT7485A is a digital temperature sensor and voltage monitor

for use in PC applications with Simple Serial Transport (SST)

interface. It can monitor its own temperature as well as the

temperature of a remote sensor diode. It can also monitor four external

voltage channels and its own supply voltage. The ADT7485A is

controlled by a single SST bidirectional data line. This device is a

fixed−address SST client where the target address is chosen by the

state of the address pin, ADD.
