Product Description
The ADT7461 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 the ADT7461. A feature of the ADT7461 is series resistance cancellation, where up to 1.5 kohms; (typical) of resistance in series with the temperature monitoring diode can be automatically cancelled from the temperature result, allowing noise filtering.
Features
 
  • On-chip and Remote Temperature Sensor
  • 0.25C Resolution/1C Accuracy on Remote Channel
  • 1C Resolution/1C Accuracy on Local Channel
  • Automatically Cancels up to 1.5 k (typical) of Resistance in Series with Remote Diode to Allow Noise Filtering
  • 2-wire SMBus Serial Interface with SMBus Alert Support
  • Programmable Over/Under Temperature Limits
  • Up to Two Over Temperature Fail-safe THERM Outputs
  • 240 A Operating Current, 5 A Standby Current
