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.
