  • Description

    The G781 is a precise digital thermometer that reports the temperature of both a remote sensor and its own package. It is commonly used in various applications such as desktop and notebook computers, central office, telecom equipment, smart battery packs, test and measurement, LAN servers, multi-chip modules, and industrial controllers. The remote sensor is a diode-connected transistor that can replace conventional thermistors or thermocouples. It offers a high level of accuracy, with a remote accuracy of ±1°C and a local accuracy of ±3°C. The G781 also features a built-in noise filtering function in the remote sensor and supports SMBus 2-Wire Serial Interface.
