The TC03 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 negative voltage source is required for temperature measurement below 0 °C. The TC02 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 TC03 (10mV/ °C). The output voltage range is 300mV at – 20 °C to 1,750mV at +125°C. Small size, low cost and low power operation make the TC02/03 suitable for a wide range of general purpose temperature measurement applications.
