www.DataSheet4U.com aTS75 LOW-VOLTAGE 2-WIRE DIGITAL TEMPERATURE SENSOR With Thermal Alarm Fully Released Specification Product Description The aTS75 is a CMOS temperature sensor with a DeltaSigma temperature-to-digital converter and a SMBus compatible serial digital interface. The aTS75 is accurate to ±2° at 25°C and to ±3°C over the range of 0°C to 100°C. The aTS75 provides digital temperature data with 9- to 12bit resolution. The default resolution is 9-bits, but for applications requiring higher resolution, the user can program the aTS75 to provide 10-, 11-, or 12-bit data. The aTS75 features a thermal alarm function with a userprogrammable trip temperature and turn-off temperature. This alarm can operate in two modes — interrupt mode and comparator mode — which allows flexibility for many types of applications. The aTS75 is available in SOIC-8 and MSOP-8 surface mount packages.
