General Description

Pin Configuration

The aTS20 is a precision CMOS temperature sensor

that provides a cost-effective solution for space-

constrained applications. The output voltage ramp of

the aTS20 has a negative slope of -11.77mV/°C. With

a supply voltage of 2.4V to 6V, the aTS20 is accurate

to ± 2°C at 25°C, and to ± 3°C over the range of −40°C

to 125°C. Reducing the supply voltage to 2.4V does

not change the negative and positive temperature

extremes. As well, the aTS20 does not require

external calibration. Calibration of each device is

performed at the factory.
