New Release Specification
General Description
The aTS50 is a high-precision CMOS temperature
sensor that provides a cost-effective solution for
applications requiring high-accuracy low-power
temperature monitoring. The aTS50 output voltage
ramp is extremely linear and has a slope of 10mV/°C.
With a supply voltage of 2.7V to 6V, the aTS50 is
accurate to ±1°C over a temperature range of
−40°C
to
125°C and has a typical room temperature accuracy of
±0.5°C. Reducing the supply voltage to 2.7V does not
change the negative and positive temperature
extremes. As well, the aTS50 does not require
external calibration. Calibration of each device is
performed at the factory.
