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.

MARKING DIAGRAM

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.
