Description
The ADT7461ARMZ-2 is a dual-channel digital thermometer integrated circuit designed for use in thermal management systems and personal computers. It is compatible with ADM1032, both at pin and register levels, and it comes with three additional features. The integrated circuit has a series resistance cancellation feature that allows noise filtering by automatically canceling up to 3 kΩ of resistance in series with the temperature-monitoring diode.
