TEMPERATURE SENSOR
PRODUCT SPECIFICATION
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.
