Parameters Sym Min Typ Max Units 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 VDD 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, CL = 80 pF, is used for AC timing measurements of output signals. 4: Resolution = Temperature Range/No. of Bits = (+255°C – -256°C) / (213) Resolution = 512/8192 = 0.0625°C/Bit |
