TL064: The output voltage range of TL064CDR is inconsistent with the specification.

Tool/software:

ⅠBasic circuit conditions:

1. a) The supply voltage of TL064 is ±5V;
2. b) The input of TL064 is DC +2.5V, and the voltage at pin 8 is tested with an oscilloscope;

Circuit design:

Ⅱ. Existing problems

According to the description in Figure 6-1 of the TL064CDR specification (August 2023 version), when the supply voltage is ±5V, its maximum output voltage should not exceed ±4.2V. However, the actual test results show that it can output ±5V;
