SST Digital Temperature

Sensor and Voltage Monitor

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

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.
