ADT7461  
+15C Temperature Monitor  
with Series Resistance  
Cancellation  
The ADT7461 is a dual-channel digital thermometer and under/over  
temperature alarm intended for use in PCs and thermal management  
systems. It is pin- and register-compatible with the ADM1032. The  
ADT7461 has three additional features: series resistance cancellation  
(where up to 3 kW (typical) of resistance in series with the temperature  
monitoring diode may be automatically cancelled from the temperature  
result, allowing noise filtering); configurable ALERT output; and an  
extended, switchable temperature measurement range. The ADT7461  
can accurately measure the temperature of a remote thermal diode to  
1°C and the ambient temperature to 3°C. The temperature  
measurement range defaults to 0°C to +127°C, compatible with the  
ADM1032, but can be switched to a wider measurement range of −55°C  
to +150°C. The ADT7461 communicates over a 2-wire serial interface  
compatible with system management bus (SMBus) standards. An  
ALERT output signals when the on-chip or remote temperature is out of  
range. The THERM output is a comparator output that allows on/off  
control of a cooling fan. The ALERT output can be reconfigured as a  
second THERM output, if required.
