3. Preventive measure against oscillation
4. Input offset prevention circuit at V
For preventing the oscillation, it is advisable to use C
characteristic fluctuation of the temperature and the frequency.
The resistance R to be series applied to C
oscillation allowance.
Since the oscillation allowance is varied according to the causes described below, perform the temperature test to
check the oscillation allowance.
In case of its use with the voltage gain G
because the phase-inversion is caused by the high frequency resulting in making the oscillation generated.
Having pre-amp (amp 1) mounted on the primary stage, this IC contains the circuit for making the amp 1 input
voltage and the NF terminal voltage equipotential.
Therefore, the offset voltage produced at the input stage is suppressed to prevent the pop noise at V
