Description

Features:

`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 V_ref AMP (r₀= 10 ) is built in, the virtual grounding impedance is about 10 . This eliminates the need for a large capacitor.
`8 speaker drivable.
