Proper cares in using IC
1. Maximum Rating
If the IC is used in the vicinity of the maximum rating, even a slight variation in conditions may cause the maximum
rating to be exceeded, thereby leading to a breakdown. Allow an ample margin of variation for supply voltage, etc.
and use the IC in the range where the maximum rating is not exceed.
2. Short between pins
If the supply voltage is applied when the space between pins is shorted, a breakdown or deterioration may occur.
When installing the IC on the board or applying the supply voltage, make sure that the space between pins is not
shorted with solder, etc.
3. Breakdown of IC attributable to inverted insertion
If the IC is inserted inversely and operated, the IC may suffer from something unusual, thereby leading to a breakdown or
deterioration of the IC. When installing the IC on the board or operating the IC, check the marked surface of IC.
Proper cares to be taken for obtaining optimum operation of IC
Set DC resistance of R1, R2 of NAB element at approximately 100k.
Determine the gain by changing RNF without chaging NAB constant (Refer to Examples of NAB constant.).
