Key Notes:

️· VREG Dependency: Many of the specifications are defined *with the condition* of a VREG (supply voltage) between 2.4V and 3.5V. This means the values might change if the supply voltage is different.
️· Units: Pay close attention to the units (µV, mV, V, mA, pF, ns, µs).
️· Conditions: Many parameters have specific conditions under which they are measured or apply (e.g., load capacitance, input signal amplitude, CS state).
