APPLICATION INFORMATION AND APPLICATION METHOD (C
ont.)
3. INPUT STAGE
The input circuit of this IC is as shown in Fig.2.
PNP TR: Q1 is provided in the input circuit so as to make its usage possible without the input coupling capacitor.
However, at pins
⑤
and
⑦
, max 60mV offset voltage is produced.
Application after checking volume slide noise is recommended.
For cutting the volume slide noise, inset the input capacitor: C
IN
in series to interrupt the DC component.

4. OSCILLATION PERVENTIVE MEASURES
For oscillation preventive capacitor C6 and C7 between the output terminal and GND, it is recommended to use
polyester film capacitor having good characteristics for temperature and for high frequency.
Since the characteristics of the capacitor is liable to be influenced by the temperature, use this capacitor after the
temperature test to check the oscillation allowance. In addition, as the position of the electrolytic capacitor has a
remarkable influence on the oscillation, connect C10 to V
CC
at the nearest possible position from power GND.
At using this application with the voltage gain reduced, oscillation is liable to be produced. Apply the capacitor after
checking enough for its capacity, type and mounting position.
5. INPUT VOLTAGE
When the excessive signal is input, turning-up is produced in the clip waveform. The turning-up point is V
IN
=
300mV

(Typ.): V

, f = 1kHz : Enough care must be taken for this phenomenon.
