3. Preventive measure against oscillation
For preventing the oscillation, it is advisable to use C4, the condenser of polyester film having small
characteristic fluctuation of the temperature and the frequency.
The condenser (C6) between input and GND is effective for preventing oscillation which is generated with a
feedback signal from a output stage.
The resistance R to be series applied to C4 is effective for phase correction of high frequency, and improves the
oscillation allowance.
(1) Voltage gain to be used (GV setting)
(2) Capacity value of condenser
(3) Kind of condenser
(4) Layout of printed board
In case of its use with the voltage gain GV reduced or with the feedback amount increased, care must be taken
because the phase-inversion is caused by the high frequency resulting in making the oscillation liable
generated.
4. Adjustment of output offset (when the power supply turn on)
As this IC is constructed with DC circuit on the pre-amp stage, it is necessary to lower a input offset or output
offset by agreement with the each leading edge time constant of the input voltage in the pre-amp stage and NF
terminal voltage.
Concretely, monitor the output DC voltage and vary the capacity value in input condenser and NF condenser
(see Fig.4)
(Reference) In case of setting the condition (GV = 40dB) with Rf = 470
