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.
