PARASTIC OSCILLATION PREVEMTING CIRCUIT
1+0.22µF parallel load,if load speaker.Recommend putting 0.1µF more than 100µF capacitors with good high frequency characteristics near ground supply voltage pins. operation less than supply voltage,parastic oscillation occurred with R=1.And recommended same value pure resistance(r) when lower than
MUTING CIRCUIT
When Mute ON.OUTPUT level saturates side.

VOLTAGE GAIN REDUCTION APPLICATION EXAMPLE Outline further Reduction
NJM2073 taking assamption,as OP-AMP Gain 44dB,minus input impedance about ),to feedback from output minus input helps reduction stabilized Voltage Gain.Fig.5 indicates model example. Here point noticed that,in order appropriate output Bias Voltage,it important keep minus input floating condition,(inserting CX),and also that when extended much reduction Gain might cause Oscillation high band phase margin.The reduction voltage gain limited around 26dB times),and when oscillation,it necessary attach oscillation stopper.Please examine value accordingly application requirement.
