The TC1023 has a temperature measure- ment 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 resis- tor to a negative voltage source is required for temperature measurement below 0 °C. The TC1024 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 TC1023 (10mV/ °C). The output voltage range is 100mV at – 20 °C to 1,750mV at +125°C. Both devices have a chip enable input that reduces supply current to 1 µA (typical) when pulled active high. In this state, the output defaults to a high resistance allowing an external reference voltage to be directly connected for A/D calibration. Small size, low cost, flexibility and low power operation make the TC1023/1024 suitable for a wide range of gen- eral purpose temperature measurement applications.
