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 ?癈 and the ambient temperature accurate to ?癈.
The temperature measurement range defaults to 0癈 to +127癈,
compatible with the ADM1032, but it can be switched to a wider
measurement range of 64癈 to +191癈.
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 ADT7461A2 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.
