SST Digital Temperature Sensor
and Voltage Monitor
1 on-chip temperature sensor
1 remote temperature sensor
Monitors up to 5 voltages
Simple Serial Transport™ (SST™) interface
The ADT7485A is a digital temperature sensor and voltage
monitor for use in PC applications with a 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.
