Product Overview
Product Description
The ADT7483A is a three-channel digital thermometer and under/over temperature alarm, intended for use in PCs and thermal management systems. It can measure the temperature in two remote locations, for example, the remote thermal diode in a CPU or GPU, or a discrete diode connected transistor. It can also measure its own ambient temperature.
Features
 
  • 1 Local and 2 Remote Temperature Sensors
  • 0.25°C Resolution/1°C Accuracy on Remote Channels
  • 1°C Resolution/1°C Accuracy on Local Channel
  • Extended, Switchable Temperature Measurement Range 0°C to +127°C (default) or 64°C to +191°C
  • 2-wire SMBus Serial Interface with SMBus Alert Support
  • Programmable Over/Under Temperature Limits
