(13) Crossorver distortion
Inverting amplifier is generete crossover distortion when feed back resistance value is small.
To supress the crosover distortion, connect a resistor between the output terminal and VSS
Then increse the bias current to enable class A output stage operation.
latch up operation. And protect the IC from abnormaly noise
Be careful of input voltage that exceed the VDD and VSS. When CMOS device have sometimes occur
If short circuit occurs between the output terminal and VDD terminal, excessive
in output current may flow and generate heat, causing destruction of the IC. Take due care.
Be careful when using the IC under strong electromagnetic field because it may malfunction.
When stress is applied to the IC through warp of the printed circuit board,
The characteristics may fluctuate due to the piezo effect.
Be careful of the warp of the printed circuit board.
When testing IC on the set board, in cases where the capacitor is connected to the low impedance,
make sure to discharge per fabrication because there is a possibility that IC may be damaged by stress.
When removing IC from the set board, it is essential to cut supply voltage.
As a countermeasure against the static electricity, observe proper grounding during fabrication process
and take due care when carrying and storage it.
The transistors in circuits may be damaged when VDD terminal and VSS terminal is shorted with the charged
output terminal capacitor.
When IC is used as a operational amplifier or as an application circuit, where oscillation is not activated
by an output capacitor,the output capacitor must be kept below 0.1[μF] in order to prevent the damage
mentioned above.
Insert the decupling capacitance between VDD and VSS, for stable operation of operational amplifier.
