GXCAS GX122

The GX122 is an SPI compatible temperature sensor available in a SOT23 - 6 package. The GX122 temperature sensor only needs a pull - up resistor to achieve a typical temperature accuracy of 0.3°C in the temperature range of - 25°C to +85°C, and the operating temperature is as high as 150°C. Programmable resolution, programmable set point and shutdown function provide versatility for any application. Low supply current and a power supply range from 2.7V to 5.5V make the GX122 an excellent candidate for low power applications. The GX122 is ideal for extended thermal measurement in a variety of communications, computer, consumer, environmental, industrial, and instrumentation applications.
