Parameters Sym Min Typ Max Units Conditions Temperature Ranges Specified Temperature Range TA -55 — +125 °C Operating Temperature Range TA -55 — +125 °C Storage Temperature Range TA -65 — +150 °C Thermal Package Resistances Thermal Resistance 8-L 3x3 DFN θ JA —56.7 — °C/W Thermal Resistance 8-L MSOP θ JA —211 — °C/W DC CHARACTERISTICS (CONTINUED) Electrical Specifications: Unless otherwise noted, all parameters apply at V DD = 2.65V to 5.5V, TA = -55°C to +125°C. Parameters Sym Min Typ Max Units Conditions 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 |
