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 V
DD
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 C
L
= 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) / (2

) = 256/1024 = 0.25°C/Bit
