Conditions
Note 1: The TC77-3.3MXX and TC77-5.0MXX will operate from a supply voltage of 2.7V to 5.5V. However, the tem-
perature accuracy of the TC77-3.3MXX and TC77-5.0MXX is specified at the nominal operating voltages of
3.3V and 5.0V, respectively. As V
DD
varies from the nominal operating value, the accuracy may be
degraded (Refer to Figures 2-6 and 2-7).
2: All time measurements are measured with respect to the 50% point of the signal.
3: Load Capacitance, C
L
= 80 pF, is used for AC timing measurements of output signals.
4: Resolution = Temperature Range/No. of Bits = (+255?/SPAN>C -256?/SPAN>C) / (2
13
)
Resolution = 512/8192 = 0.0625癈/Bit
