ADT7461A  
+15C Temperature Monitor  
with Series Resistance  
Cancellation  
The ADT7461A is a dual−channel digital thermometer and  
undertemperature/overtemperature alarm, intended for use in PCs and  
thermal management systems. It is pin− and register−compatible with the  
ADM1032 and ADT7461. A feature of the ADT7461A is series  
resistance cancellation, where up to 1.5 kW (typical) of resistance in  
series with the temperature monitoring diode can be automatically  
cancelled from the temperature result, allowing noise filtering. The  
ADT7461A has a configurable ALERT output and an extended,  
switchable temperature measurement range.

The ADT7461A can measure the temperature of a remote thermal  
diode accurate to 1°C and the ambient temperature accurate to 3°C.  
The temperature measurement range defaults to 0°C to +127°C,  
compatible with the ADM1032, but it can be switched to a wider  
measurement range of −64°C to +191°C.  
The ADT7461A communicates over a 2−wire serial interface,  
compatible with system management bus (SMBus) standards. The  
default SMBus address of the ADT7461A is 0x4C. An ADT7461A−2 is  
available with an SMBus address of 0x4D. This is useful if more than one  
ADT7461A is used on the same SMBus.

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.
