. Preamplifier muting and preamplifier output on/off can be . . . . implemented with one pin. This IC can easily be used to construct a set with a radio. The power amplifier needs no input/output coupling capacitor. A high-frequency cut capacitor is connected to the preamplifier input pin and the power amplifier input pin. (Anti-buzz provision) Because Vref AMP (r0 = 10 Ω) is built in, the virtual grounding impedance is about 10 Ω. This eliminates the need for a large capacitor. 8 Ω speaker dri.
