GENERAL DESCRIPTION
The ADT7483A1 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. The temperature of the remote thermal diode and ambient temperature can be accurately measured to ±1°C. The temperature measurement range defaults to 0°C to 127°C, compatible with ADM1032, but can be switched to a wider measurement range, from −64°C to +191°C.

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
    Offset registers for system calibration
    Up to 2 overtemperature fail-safe THERM outputs
    Small 16-lead QSOP package
    240 μA operating current, 5 μA standby current

APPLICATIONS
    Desktop and notebook computers
    Industrial controllers
    Smart batteries
    Automotive
    Embedded systems
    Burn-in applications
    Instrumentation
