(3) Bias block

(4) Amplifier block

The components connected to pins 2, 3, and 4 set the

bias point and V^ODC. When pin 2 is open circuit, and VCC

= 1.25V, the output pin VODC voltage is internally set to

1/2V^CC. By connecting a resistor to pin 2 and changing

the voltage divider ratio, it is possible to vary V^ODC.

Pins 3 and 4 are shorted and connected to earth via an

electrolytic capacitor to generate the bias point. When a

33µF component is used, it is possible to obtain 45dB of

ripplerejection. Thiscanbeimprovedifpinsareindepen-

dently grounded through capacitors.

The amplifier circuits have a fixed gain of G^V= 21dB. The

negative-feedback circuits are on the chip, and the

ground point of the negative-feedback circuit uses the

bias point as its reference, so connect the input poten-

tiometer to the bias point pins (3 and 4). Connect bypass

capacitors to the output pin to prevent oscillation. When

to reduce unnecessary radiation from the power amplifi-

ers by connecting CR circuits to pins 6 and 11.
