ADT7482 Datasheet | onsemi

feature of the ADT7482 is series resistance cancellation where up to 1.5 k W (typical) of resistance in series with each of the temperature monitoring diodes can be automatically cancelled from the temperature result, allowing noise filtering. The temperature of the remote thermal diodes and ambient temperature can be measured accurate to 1C. The temperature measurement range, which defaults to 0C to 127C, can be switched to a wider measurement range of from - 55C to +150C. The ADT7482 municates over a 2-wire serial interface patible with System Management Bus (SMBus) standards. The default address of the ADT7482 is 0x4C. An ALERT output signals when the on-chip or remote temperature is outside the programmed limits. The THERM output is a parator output that allows on/off control of a cooling fan. The ALERT output can be reconfigured as a second THERM output if required. Features - 1 Local and 2 Remote Temperature Sensors - 0.25C Resolution/1C Accuracy on Remote Channels - 1C...
