* Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect device reliability.

The TC1023/1024 temperature sensors furnish a linearized output voltage directly proportional to measured temperature. The TC1023 has a temperature measurement range of 20 to +100. Its output voltage is directly calibrated in degrees Centigrade (i.e., V_OUT = 10mV/ x Temperature ). An external pull-down resistor to a negative voltage source is required for temperature measurement below 0.

The TC1024 has a temperature measurement range of 20 to +125, and operates with a single supply. It has
the same output voltage slope with temperature as the TC1023 (10mV/). The output voltage range is 100mV at
20to 1,750mV at +125. Both devices have a chip enable input that reduces supply current to 1mA (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 general
purpose temperature measurement applications.
