GENERAL DESCRIPTION
The ADT7482¹ is a three-channel digital thermometer and undertemperature/overtemperature alarm for PCs and thermal management systems. It can measure the temperature in two remote locations, such as in the remote thermal diode in a CPU or GPU, or using a discrete diode connected transistor. This device also measures 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
    Automatically cancels up to 1.5 kΩ (typ) of resistance in series with the remote sensors
    Extended, switchable temperature measurement range 0°C to +127°C (default) or −55°C to +150°C
    2-wire SMBus serial interface with SMBus alert support
    Programmable overtemperature/undertemperature limits
    Offset registers for system calibration
    Up to 2 overtemperature fail-safe THERM outputs
    Small, 10-lead MSOP package
    240 μA operating current, 5 μA standby current
