Note 1: The TC72-2.8MXX, TC72-3.3MXX and TC72-5.0MXX will operate from a supply voltage of 2.65V to 5.5V. However, the
TC72-2.8MXX, TC72-3.3MXX and TC72-5.0MXX are tested and specified at the nominal operating voltages of 2.8V,
3.3V and 5.0V respectively. As VDD varies from the nominal operating value, the accuracy may be degraded. Refer to
Figure 2-5 and Figure 2-6.
2: Measured with a load of CL = 50 pF on the SDO output pin of the TC72.
3: All time measurements are measured with respect to the 50% point of the signal, except for the SCK rise and fall times.
The rise and fall times are defined as the 10% to 90% transition time.
4: Resolution = Temperature Range/No. of Bits = (+127°C – -128°C) / (210) = 256/1024 = 0.25°C/Bit
