Feature Description

The TMP63 has good linear behaviour across the whole temperature range, but a small non-linearity can be observed as well as supply dependence. To fabricate the TMP63, the engineer can use a special silicon process where the device key characteristics—the temperature coefficient resistance (TCR) and nominal resistance (R25)—are controlled by the doping level and active region area. Note that the TMP63 has an active area and a substrate due to the polarized terminals of the device. The positive terminal should be connected to the highest potential, while the negative terminal (which is tied to the substrate internally) should be connected to the lowest potential. Equation 1 can help the user approximate the TCR.

Table 1 and Table 2 show the typical resistance, resistance spread, and maximum expected error across temperature using a direct ideal bias current or an ideal voltage bias in a divider circuit. The tables provided are for specific applications. Table 1 is for constant current applications supplying 20 µA of constant current. Table 2 is for a circuit having a bias voltage of 2.5 V supplying a resistor divider consisting of a top resistor of 100 kΩ with the TMP63 on the bottom. These tables are not to be used if operating either circuit under different currents, bias voltages or different Resistor values. New tables will be required based on your specific design.

Equation 1. TCR (ppm/°C) = (RT2 – RT1) / ((T2 – T1) × R(T2+T1)/2)

Below are the definitions of the key terms used throughout this document:

  • ISns: Current flowing through the TMP63.
  • VSns: Voltage across the two TMP63 terminals.
  • IBias: Current supplied by the biasing circuit.
  • VBias: Voltage supplied by the biasing circuit.
  • VTemp: Output voltage that corresponds to the measured temperature. Note that this is different from VSns. In the use case of a voltage divider circuit with the TMP63 in the high side, VTemp is taken across RBias.

Changing the specified current will require a new 4th order polynomial to create a resistance table for your design
