LM82 - Remote Diode and Local Digital Temperature Sensor

General Description

The LM82 is a digital temperature sensor with a 2 wire serial interface that senses the voltage and thus the temperature of a remote diode using a DeltaSigma analog-to-digital converter with a digital overtemperature detector.

Key Features

  • 1.
  • 2 Accurately Senses Die Temperature of Remote ICs, or Diode Junctions.
  • On-board Local Temperature Sensing.
  • SMBus and I2C Compatible Interface, Supports SMBus 1.1.
