piezoelectric effect. Therefore, pay attention to warpage or bending of a board.
The “Input Bias Current [I
Therefore, because the differential amplified circuit of the input stage will not be balanced during comparison
(when comparator is active), the input current will flow, with twice the amount of current, to a pin with low potential.
When the voltage of input/output pin exceeds the absolute maximum rating, it may cause degradation of
When the supply voltage does not meet the condition of electrical characteristics, the range of common-mode
