SST Digital Temperature Sensor
and Voltage Monitor
ADT7488A
GENERAL DESCRIPTION
The ADT7488A is a simple digital temperature sensor for use in
PC applications with Simple Serial Transport (SST) interface. It
can monitor its own temperature as well as the temperature of
two remote sensor diodes. It also measures the processor core
voltage, VCCP; a 2.5 V supply voltage; and its own supply voltage,
VCC. The ADT7488A is controlled by an SST single
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.
