Product Overview
Product Description
The ADT7461 is a dual-channel digital thermometer and under/over temperature alarm intended for use in PCs and thermal management systems. It is pin- and register-compatible with the ADM1032. The ADT7461 has three additional features: series resistance cancellation (where up to 3 kΩ (typical) of resistance in series with the temperature monitoring diode may be automatically cancelled from the temperature result, allowing noise filtering); configurable ~ALERT output; and an extended, switchable temperature measurement range.
Features
 
  • On-chip and Remote Temperature Sensor
  • 0.25°C Resolution/1°C Accuracy on Remote Channel
  • 1°C Resolution/3°C Accuracy on Local Channel
  • Automatically Cancels up to 3 kΩ (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
  • 170 µA Operating Current, 5.5 µA Standby Current
