GENERAL DESCRIPTION
output voltage directly proportional to measured tempera-
ture. The TC03 has a temperature measurement range of
– 20 C to +100 C. Its output voltage is directly calibrated in
degrees Centigrade (i.e. V
source is required for temperature measurement below
0 C.
– 20 C to +125 C, and operates with a single supply. It has
the same output voltage slope with temperature as the
TC03 (10mV/ C). The output voltage range is 300mV at
– 20 C to 1,750mV at +125 C.
TC02/03 suitable for a wide range of general purpose
temperature measurement applications.

... These devices have a limited ability to drive heavy capacitive loads. Loads of 50pF (to ground) can be driven directly. For heavier loads (or greater) resistor should be placed in series with the output for decoupling.
