LOW- OLTAGE 2-WIRE DIGITAL TEMPERATURE SENSOR
With Thermal Alarm
aTS75
PRODUCT SPECIFICATION

Product Description
The aTS75 is a CMOS temperature sensor with a Delta-
Sigma 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 12-
bit 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 user-
programmable 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.
