Accurate Measurement

The AD590 is a small temperature
transducer that converts a
temperature input into a proportional
current output.

The advanced technology in the
AD590 is especially suited for
special temperature measurement
and control applications between

-55 and 150°C (-67 to 302°F) when
solid state reliability, linearity and
accuracy are required. The AD590
can be used to determine minimum,
average, and differential
temperatures, in addition to being
used for thermocouple cold junction
compensation and temperature
control applications. The size and
responsiveness of the AD590 make
it perfect for uses where size is a
consideration, such as on PC
boards or heat sinks.

Just power up and measure
absolute temperature (Kelvin).
No linearization, amplification
or cold junction compensation is
required (Fig. 1). To convert reading
to °C, subtract 273.15.
