GENERAL DESCRIPTION
The TC1132/33 temperature sensors furnish a linear-
ized output voltage directly proportional to measured tem-
perature. The TC1133 has a temperature measurement
range of – 20
°C to +100°C. Its output voltage is directly
calibrated in degrees Centigrade (i.e. VOUT = 10mV/°C x
Temperature
°C). An external pull-down resistor to a nega-
tive voltage source is required for temperature measure-
ment below 0
°C.
The TC1132 has a temperature measurement range of
– 20
°C to +125°C, and operates with a single supply. It has
the same output voltage slope with temperature as the
TC1133 (10mV/
°C).
Small size, low cost and low power operation make the
TC1132/33 suitable for a wide range of general purpose
temperature measurement applications.
